If you're already doing a matrix multiply (adding a bias term, for instance) the easiest way to do this is directly with the sgemm method.

set beta to -1
pass in your bias terms as C (the last argument)

If you aren't doing a multiply beforehand, the best way is with the saxpy method.

set a to -1
pass the matrix you want to subtract from as X
pass the matrix you want to subtract with as Y

Please let me know if this helps you.
