| * \ingroup Core_Module |
| * |
| * \brief Expression of a fixed-size or dynamic-size block |
| * |
| * \tparam XprType the type of the expression in which we are taking a block |
| * \tparam BlockRows the number of rows of the block we are taking at compile time (optional) |
| * \tparam BlockCols the number of columns of the block we are taking at compile time (optional) |
| * \tparam InnerPanel is true, if the block maps to a set of rows of a row major matrix or |
| * to set of columns of a column major matrix (optional). The parameter allows to determine |
| * at compile time whether aligned access is possible on the block expression. |
| * |
| * This class represents an expression of either a fixed-size or dynamic-size block. It is the return |
| * type of DenseBase::block(Index,Index,Index,Index) and DenseBase::block<int,int>(Index,Index) and |
| * most of the time this is the only way it is used. |
| * |
| * However, if you want to directly manipulate block expressions, |
| * for instance if you want to write a function returning such an expression, you |
| * will need to use this class. |
| * |
| * Here is an example illustrating the dynamic case: |
| * \include class_Block.cpp |
| * Output: \verbinclude class_Block.out |
| * |
| * \note Even though this expression has dynamic size, in the case where \a XprType |
| * has fixed size, this expression inherits a fixed maximal size which means that evaluating |
| * it does not cause a dynamic memory allocation. |
| * |
| * Here is an example illustrating the fixed-size case: |
| * \include class_FixedBlock.cpp |
| * Output: \verbinclude class_FixedBlock.out |
| * |
| * \sa DenseBase::block(Index,Index,Index,Index), DenseBase::block(Index,Index), class VectorBlock |
