* \ingroup Core_Module

|
*
|
||
|
|
* \brief Expression of a fixed-size or dynamic-size block
|
||
|
|
*
|
||
|
|
* \param XprType the type of the expression in which we are taking a block
|
||
|
|
* \param BlockRows the number of rows of the block we are taking at compile time (optional)
|
||
|
|
* \param BlockCols the number of columns of the block we are taking at compile time (optional)
|
||
|
|
*
|
||
|
|
* 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 maniputate 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
