Detailed Description

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

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

Parameters:

XprType	the type of the expression in which we are taking a block
BlockRows	the number of rows of the block we are taking at compile time (optional)
BlockCols	the number of columns of the block we are taking at compile time (optional)
_DirectAccessStatus
