However matmat is done, row-major vs column-major for both matrices shouldn't make a difference (for square matrices at least). I don't know if tiling is done

However matmat is done, row-major vs column-major for both matrices shouldn't make a difference (for square matrices at least). I don't know if tiling is done for matvec. I don't think it makes sense there, but I didn't think about it too hard.
