Is there an IPP API for this purpose ?
The 3rd axis (Z) is consecutive in RAM: Z1, Z2, ...,Zk. Each Zi belongs to a different 2D matrix.
Each ROW in 2D matrix is consecutive in RAM.
Could you explain more clear for you question? for example take M=4, N=3, K=2 as an example. What's the original store pattern in RAM, and what's your expectation after calling IPP API for the complex float matrix? It's better list out the 24 complex data in RAM for both before calling IPP and after IPP.
