Hi,
The code snippet looks fine. However the working really depends on how
the memory for the matrices is allocated and how they are initialized.
Can you please check to see it the matrices are initialized correctly and
that you have allocated contiguous memory.
Also it would be nice if we have more information on initialization and
the possible use of pointers in your code.
Thanks,
Nihar.
