Detailed Description

template<typename XprType, int BlockRows, int BlockCols, bool InnerPanel>
class Eigen::Block< XprType, BlockRows, BlockCols, InnerPanel >

Expression of a fixed-size or dynamic-size block.

Parameters:
XprTypethe type of the expression in which we are taking a block
BlockRowsthe number of rows of the block we are taking at compile time (optional)
BlockColsthe 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:

Output:

Note:
Even though this expression has dynamic size, in the case where 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:

Output:
