| * \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 | |
