gemm with k = 0 does not execute C = beta * C

Issue #33 new
Wajih Halim Boukaram created an issue

I’ve been having issues using the non-uniform batch gemm where some of the operations have the parameter k = 0 (i.e. the operands A and B have zero columns/rows), but m and n are not zero. I expected the operation to continue for beta != 1 and complete C = beta * C, but it seems the gemm returns if k = 0 regardless of m and n. This leads to different results when switching from a regular CPU gemm to a GPU gemm using magma.
