Detailed description

template<uint32 BLOCKSIZE, typename T, block_strided_layout LAYOUT = ROW_MAJOR_LAYOUT>
struct cugar::block_strided_iterator< BLOCKSIZE, T, LAYOUT >

Wrapper class to create a block-strided iterator out of another base iterator, i.e:

it[ j ] = base[ (j / BLOCKSIZE) * stride + (j %% BLOCKSIZE) ]

or:

it[ j ] = base[ (j %% BLOCKSIZE) * stride + (j / BLOCKSIZE) ]

depending on whether the alignment is ROW_MAJOR or COLUMN_MAJOR

#include <strided_iterator.h>
