advance_iterator looks general enough.
What *is* an advance_iterator?
FWIW:
fusion::advance_iterator< Sequence, // the sequence to advance over Stride, // number of positions in underlying //sequence to move on 'next' StridedPosition, // underlying sequence::position * // Stride + Offset Offset // offset in underlying sequence units
The main use is to return a column in a linear sequence representing a matrix.
That's a well-known idea already in the literature;
Its not just an idea. I got one that works with fusion :-) it's known as a
"strided iterator." Can we use the common terminology?
OK, but it doesnt sound very cool, compared to advance_iterator. IMO everything in fusion should have a cool name :-) Same with inner_product. dot_product is way cooooler. regards Andy Little
