| /** \class MatrixBase |
| * \ingroup Core_Module |
| * |
| * \brief Base class for all dense matrices, vectors, and expressions |
| * |
| * This class is the base that is inherited by all matrix, vector, and related expression |
| * types. Most of the Eigen API is contained in this class, and its base classes. Other important |
| * classes for the Eigen API are Matrix, and VectorwiseOp. |
| * |
| * Note that some methods are defined in other modules such as the \ref LU_Module LU module |
| * for all functions related to matrix inversions. |
| * |
| * \tparam Derived is the derived type, e.g. a matrix type, or an expression, etc. |
| * |
| * When writing a function taking Eigen objects as argument, if you want your function |
| * to take as argument any matrix, vector, or expression, just let it take a |
| * MatrixBase argument. As an example, here is a function printFirstRow which, given |
| * a matrix, vector, or expression \a x, prints the first row of \a x. |
| * |
| * \code |
| template<typename Derived> |
| void printFirstRow(const Eigen::MatrixBase<Derived>& x) |
| { |
| cout << x.row(0) << endl; |
| } |
| * \endcode |
| * |
| * This class can be extended with the help of the plugin mechanism described on the page |
| * \ref TopicCustomizingEigen by defining the preprocessor symbol \c EIGEN_MATRIXBASE_PLUGIN. |
| * |
| * \sa \ref TopicClassHierarchy |
