I’m pretty sure BLAS will tile out the matrix multiplication internally anyway, so it doesn’t matter. At least for matmat would, is matvec special?

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.
