- * \brief A matrix or vector expression mapping an existing array of data.
- *
- * \tparam PlainObjectType the equivalent matrix type of the mapped data
- * \tparam MapOptions specifies the pointer alignment in bytes. It can be: \c #Aligned128, \c #Aligned64, \c #Aligned32, \c #Aligned16, \c #Aligned8 or \c #Unaligned.
- * The default is \c #Unaligned.
- * \tparam StrideType optionally specifies strides. By default, Map assumes the memory layout
- * of an ordinary, contiguous array. This can be overridden by specifying strides.
- * The type passed here must be a specialization of the Stride template, see examples below.
- *
- * This class represents a matrix or vector expression mapping an existing array of data.
- * It can be used to let Eigen interface without any overhead with non-Eigen data structures,
- * such as plain C arrays or structures from other libraries. By default, it assumes that the
- * data is laid out contiguously in memory. You can however override this by explicitly specifying
- * inner and outer strides.
- *
- * Here's an example of simply mapping a contiguous array as a \ref TopicStorageOrders "column-major" matrix:
- * \include Map_simple.cpp
- * Output: \verbinclude Map_simple.out
- *
- * If you need to map non-contiguous arrays, you can do so by specifying strides:
- *
- * Here's an example of mapping an array as a vector, specifying an inner stride, that is, the pointer
- * increment between two consecutive coefficients. Here, we're specifying the inner stride as a compile-time
- * fixed value.
- * \include Map_inner_stride.cpp
- * Output: \verbinclude Map_inner_stride.out

+ * \tparam PlainObjectType the equivalent matrix type of the mapped data
+ * \tparam MapOptions specifies the pointer alignment in bytes. It can be: \c #Aligned128, \c #Aligned64, \c #Aligned32,
+ * \c #Aligned16, \c #Aligned8 or \c #Unaligned. The default is \c #Unaligned. \tparam StrideType optionally specifies

+ * specifying strides. The type passed here must be a specialization of the Stride template, see examples below.
+ *
+ * This class represents a matrix or vector expression mapping an existing array of data.
+ * It can be used to let Eigen interface without any overhead with non-Eigen data structures,
+ * such as plain C arrays or structures from other libraries. By default, it assumes that the
+ * data is laid out contiguously in memory. You can however override this by explicitly specifying
+ * inner and outer strides.
+ *
+ * Here's an example of simply mapping a contiguous array as a \ref TopicStorageOrders "column-major" matrix:
+ * \include Map_simple.cpp
+ * Output: \verbinclude Map_simple.out
+ *
+ * If you need to map non-contiguous arrays, you can do so by specifying strides:
+ *
+ * Here's an example of mapping an array as a vector, specifying an inner stride, that is, the pointer
+ * increment between two consecutive coefficients. Here, we're specifying the inner stride as a compile-time
+ * fixed value.
+ * \include Map_inner_stride.cpp
+ * Output: \verbinclude Map_inner_stride.out
+ *
+ * Here's an example of mapping an array while specifying an outer stride. Here, since we're mapping
+ * as a column-major matrix, 'outer stride' means the pointer increment between two consecutive columns.

- * What it does:

- * - if type T has a member typedef Eigen_BaseClassForSpecializationOfGlobalMathFuncImpl, then
- * global_math_functions_filtering_base<T>::type is a typedef for it.
- * - otherwise, global_math_functions_filtering_base<T>::type is a typedef for T.
- *
- * How it's used:
- * To allow to defined the global math functions (like sin...) in certain cases, like the Array expressions.
- * When you do sin(array1+array2), the object array1+array2 has a complicated expression type, all what you want to know
- * is that it inherits ArrayBase. So we implement a partial specialization of sin_impl for ArrayBase<Derived>.
- * So we must make sure to use sin_impl<ArrayBase<Derived> > and not sin_impl<Derived>, otherwise our partial specialization
- * won't be used. How does sin know that? That's exactly what global_math_functions_filtering_base tells it.
- *
- * How it's implemented:
- * SFINAE in the style of enable_if. Highly susceptible of breaking compilers. With GCC, it sure does work, but if you replace
- * the typename dummy by an integer template parameter, it doesn't work anymore!

- * \brief The matrix class, also used for vectors and row-vectors
- *
- * The %Matrix class is the work-horse for all \em dense (\ref dense "note") matrices and vectors within Eigen.
- * Vectors are matrices with one column, and row-vectors are matrices with one row.
- *
- * The %Matrix class encompasses \em both fixed-size and dynamic-size objects (\ref fixedsize "note").
- *
- * The first three template parameters are required:
- * \tparam Scalar_ Numeric type, e.g. float, double, int or std::complex<float>.
- * User defined scalar types are supported as well (see \ref user_defined_scalars "here").
- * \tparam Rows_ Number of rows, or \b Dynamic
- * \tparam Cols_ Number of columns, or \b Dynamic
- *
- * The remaining template parameters are optional -- in most cases you don't have to worry about them.
- * \tparam Options_ A combination of either \b #RowMajor or \b #ColMajor, and of either
- * \b #AutoAlign or \b #DontAlign.
- * The former controls \ref TopicStorageOrders "storage order", and defaults to column-major. The latter controls alignment, which is required
- * for vectorization. It defaults to aligning matrices except for fixed sizes that aren't a multiple of the packet size.
- * \tparam MaxRows_ Maximum number of rows. Defaults to \a Rows_ (\ref maxrows "note").
- * \tparam MaxCols_ Maximum number of columns. Defaults to \a Cols_ (\ref maxrows "note").
- *
- * Eigen provides a number of typedefs covering the usual cases. Here are some examples:
- *
- * \li \c Matrix2d is a 2x2 square matrix of doubles (\c Matrix<double, 2, 2>)
- * \li \c Vector4f is a vector of 4 floats (\c Matrix<float, 4, 1>)
- * \li \c RowVector3i is a row-vector of 3 ints (\c Matrix<int, 1, 3>)
- *
- * \li \c MatrixXf is a dynamic-size matrix of floats (\c Matrix<float, Dynamic, Dynamic>)
- * \li \c VectorXf is a dynamic-size vector of floats (\c Matrix<float, Dynamic, 1>)
- *
- * \li \c Matrix2Xf is a partially fixed-size (dynamic-size) matrix of floats (\c Matrix<float, 2, Dynamic>)
- * \li \c MatrixX3d is a partially dynamic-size (fixed-size) matrix of double (\c Matrix<double, Dynamic, 3>)
- *
- * See \link matrixtypedefs this page \endlink for a complete list of predefined \em %Matrix and \em Vector typedefs.
- *
- * You can access elements of vectors and matrices using normal subscripting:
- *
- * \code
- * Eigen::VectorXd v(10);
- * v[0] = 0.1;
- * v[1] = 0.2;
- * v(0) = 0.3;
- * v(1) = 0.4;
- *
- * Eigen::MatrixXi m(10, 10);
- * m(0, 1) = 1;
- * m(0, 2) = 2;
- * m(0, 3) = 3;
- * \endcode
- *
- * This class can be extended with the help of the plugin mechanism described on the page
- * \ref TopicCustomizing_Plugins by defining the preprocessor symbol \c EIGEN_MATRIX_PLUGIN.

- * \ingroup Core_Module
- *
- * \brief Holds information about the various numeric (i.e. scalar) types allowed by Eigen.
- *
- * \tparam T the numeric type at hand
- *
- * This class stores enums, typedefs and static methods giving information about a numeric type.
- *
- * The provided data consists of:
- * \li A typedef \c Real, giving the "real part" type of \a T. If \a T is already real,
- * then \c Real is just a typedef to \a T. If \a T is \c std::complex<U> then \c Real
- * is a typedef to \a U.
- * \li A typedef \c NonInteger, giving the type that should be used for operations producing non-integral values,
- * such as quotients, square roots, etc. If \a T is a floating-point type, then this typedef just gives
- * \a T again. Note however that many Eigen functions such as internal::sqrt simply refuse to
- * take integers. Outside of a few cases, Eigen doesn't do automatic type promotion. Thus, this typedef is
- * only intended as a helper for code that needs to explicitly promote types.
- * \li A typedef \c Literal giving the type to use for numeric literals such as "2" or "0.5". For instance, for \c std::complex<U>, Literal is defined as \c U.
- * Of course, this type must be fully compatible with \a T. In doubt, just use \a T here.
- * \li A typedef \a Nested giving the type to use to nest a value inside of the expression tree. If you don't know what
- * this means, just use \a T here.
- * \li An enum value \a IsComplex. It is equal to 1 if \a T is a \c std::complex
- * type, and to 0 otherwise.
- * \li An enum value \a IsInteger. It is equal to \c 1 if \a T is an integer type such as \c int,
- * and to \c 0 otherwise.
- * \li Enum values ReadCost, AddCost and MulCost representing a rough estimate of the number of CPU cycles needed
- * to by move / add / mul instructions respectively, assuming the data is already stored in CPU registers.
- * Stay vague here. No need to do architecture-specific stuff. If you don't know what this means, just use \c Eigen::HugeCost.
- * \li An enum value \a IsSigned. It is equal to \c 1 if \a T is a signed type and to 0 if \a T is unsigned.
- * \li An enum value \a RequireInitialization. It is equal to \c 1 if the constructor of the numeric type \a T must
- * be called, and to 0 if it is safe not to call it. Default is 0 if \a T is an arithmetic type, and 1 otherwise.
- * \li An epsilon() function which, unlike <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/epsilon">std::numeric_limits::epsilon()</a>,
- * it returns a \a Real instead of a \a T.
- * \li A dummy_precision() function returning a weak epsilon value. It is mainly used as a default
- * value by the fuzzy comparison operators.
- * \li highest() and lowest() functions returning the highest and lowest possible values respectively.
- * \li digits() function returning the number of radix digits (non-sign digits for integers, mantissa for floating-point). This is
- * the analogue of <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/digits">std::numeric_limits<T>::digits</a>
- * which is used as the default implementation if specialized.
- * \li digits10() function returning the number of decimal digits that can be represented without change. This is
- * the analogue of <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/digits10">std::numeric_limits<T>::digits10</a>
- * which is used as the default implementation if specialized.
- * \li max_digits10() function returning the number of decimal digits required to uniquely represent all distinct values of the type. This is
- * the analogue of <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/max_digits10">std::numeric_limits<T>::max_digits10</a>
- * which is used as the default implementation if specialized.
- * \li min_exponent() and max_exponent() functions returning the highest and lowest possible values, respectively,
- * such that the radix raised to the power exponent-1 is a normalized floating-point number. These are equivalent to
- * <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/min_exponent">std::numeric_limits<T>::min_exponent</a>/
- * <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/max_exponent">std::numeric_limits<T>::max_exponent</a>.
- * \li infinity() function returning a representation of positive infinity, if available.
- * \li quiet_NaN function returning a non-signaling "not-a-number", if available.

- *
- * This class provides a way to write non-template functions taking Eigen objects as parameters while limiting the number of copies.
- * A Ref<> object can represent either a const expression or a l-value:
- * \code
- * // in-out argument:
- * void foo1(Ref<VectorXf> x);
- *
- * // read-only const argument:
- * void foo2(const Ref<const VectorXf>& x);
- * \endcode
- *
- * In the in-out case, the input argument must satisfy the constraints of the actual Ref<> type, otherwise a compilation issue will be triggered.
- * By default, a Ref<VectorXf> can reference any dense vector expression of float having a contiguous memory layout.
- * Likewise, a Ref<MatrixXf> can reference any column-major dense matrix expression of float whose column's elements are contiguously stored with
- * the possibility to have a constant space in-between each column, i.e. the inner stride must be equal to 1, but the outer stride (or leading dimension)
- * can be greater than the number of rows.
- *
- * In the const case, if the input expression does not match the above requirement, then it is evaluated into a temporary before being passed to the function.
- * Here are some examples:
- * \code
- * MatrixXf A;
- * VectorXf a;
- * foo1(a.head()); // OK
- * foo1(A.col()); // OK
- * foo1(A.row()); // Compilation error because here innerstride!=1
- * foo2(A.row()); // Compilation error because A.row() is a 1xN object while foo2 is expecting a Nx1 object
- * foo2(A.row().transpose()); // The row is copied into a contiguous temporary
- * foo2(2*a); // The expression is evaluated into a temporary
- * foo2(A.col().segment(2,4)); // No temporary
- * \endcode
- *
- * The range of inputs that can be referenced without temporary can be enlarged using the last two template parameters.
- * Here is an example accepting an innerstride!=1:
- * \code
- * // in-out argument:
- * void foo3(Ref<VectorXf,0,InnerStride<> > x);
- * foo3(A.row()); // OK
- * \endcode
- * The downside here is that the function foo3 might be significantly slower than foo1 because it won't be able to exploit vectorization, and will involve more
- * expensive address computations even if the input is contiguously stored in memory. To overcome this issue, one might propose to overload internally calling a
- * template function, e.g.:
- * \code
- * // in the .h:
- * void foo(const Ref<MatrixXf>& A);
- * void foo(const Ref<MatrixXf,0,Stride<> >& A);
- *
- * // in the .cpp:
- * template<typename TypeOfA> void foo_impl(const TypeOfA& A) {
- * ... // crazy code goes here
- * }
- * void foo(const Ref<MatrixXf>& A) { foo_impl(A); }
- * void foo(const Ref<MatrixXf,0,Stride<> >& A) { foo_impl(A); }
- * \endcode

- * The inner stride is the pointer increment between two consecutive entries within a given row of a

- * The outer stride is the pointer increment between two consecutive rows of a row-major matrix or

- * These two values can be passed either at compile-time as template parameters, or at runtime as

- * Indeed, this class takes two template parameters:

- * \tparam InnerStrideAtCompileTime_ the inner stride, or Dynamic if you want to specify it at runtime.
- *
- * Here is an example:
- * \include Map_general_stride.cpp

- *
- * Both strides can be negative. However, a negative stride of -1 cannot be specified at compile time
- * because of the ambiguity with Dynamic which is defined to -1 (historically, negative strides were

- * \tparam ExpressionType the type of the object on which to do partial reductions
- * \tparam Direction indicates whether to operate on columns (#Vertical) or rows (#Horizontal)
- *
- * This class represents a pseudo expression with broadcasting and partial reduction features.
- * It is the return type of DenseBase::colwise() and DenseBase::rowwise()
- * and most of the time this is the only way it is explicitly used.
- *
- * To understand the logic of rowwise/colwise expression, let's consider a generic case `A.colwise().foo()`
- * where `foo` is any method of `VectorwiseOp`. This expression is equivalent to applying `foo()` to each
- * column of `A` and then re-assemble the outputs in a matrix expression:
- * \code [A.col(0).foo(), A.col(1).foo(), ..., A.col(A.cols()-1).foo()] \endcode
- *
- * Example: \include MatrixBase_colwise.cpp
- * Output: \verbinclude MatrixBase_colwise.out
- *
- * The begin() and end() methods are obviously exceptions to the previous rule as they
- * return STL-compatible begin/end iterators to the rows or columns of the nested expression.
- * Typical use cases include for-range-loop and calls to STL algorithms:
- *
- * Example: \include MatrixBase_colwise_iterator_cxx11.cpp
- * Output: \verbinclude MatrixBase_colwise_iterator_cxx11.out
- *
- * For a partial reduction on an empty input, some rules apply.
- * For the sake of clarity, let's consider a vertical reduction:
- * - If the number of columns is zero, then a 1x0 row-major vector expression is returned.
- * - Otherwise, if the number of rows is zero, then
- * - a row vector of zeros is returned for sum-like reductions (sum, squaredNorm, norm, etc.)
- * - a row vector of ones is returned for a product reduction (e.g., <code>MatrixXd(n,0).colwise().prod()</code>)
- * - an assert is triggered for all other reductions (minCoeff,maxCoeff,redux(bin_op))

+ * This function returns an object embedding both a compile-time integer \c N, and a fallback runtime value \a val.
+ *
+ * \tparam N the compile-time integer value
+ * \param val the fallback runtime integer value
+ *
+ * This function is a more general version of the \ref fix identifier/function that can be used in template code
+ * where the compile-time value could turn out to actually mean "undefined at compile-time". For positive integers
+ * such as a size or a dimension, this case is identified by Eigen::Dynamic, whereas runtime signed integers
+ * (e.g., an increment/stride) are identified as Eigen::DynamicIndex. In such a case, the runtime value \a val
+ * will be used as a fallback.
+ *
+ * A typical use case would be:
+ * \code
+ * template<typename Derived> void foo(const MatrixBase<Derived> &mat) {
+ * const int N = Derived::RowsAtCompileTime==Dynamic ? Dynamic : Derived::RowsAtCompileTime/2;
+ * const int n = mat.rows()/2;
+ * ... mat( seqN(0,fix<N>(n) ) ...;
+ * }
+ * \endcode
+ * In this example, the function Eigen::seqN knows that the second argument is expected to be a size.
+ * If the passed compile-time value N equals Eigen::Dynamic, then the proxy object returned by fix will be dissmissed,
+ * and converted to an Eigen::Index of value \c n. Otherwise, the runtime-value \c n will be dissmissed, and the
