actually one should provide both storage formats.
Art least I'm confronted with (dense, rather large) matrix
multiplications of the form A_i * B_i, where A_i always appear on
the left, and B_i appears on the right.
So using different storage layouts, I can increase performance
since no strides appear.

Best wishes,

I can improve
