Copy imaginary part of mxGPUArray
#include "gpu/mxGPUArray.h" mxGPUArray* mxGPUCopyImag(mxGPUArray const * const mgp)
mgpPointer to an mxGPUArray. The target
gpuArray must be full, not sparse.
Pointer to an mxGPUArray.
mxGPUCopyImag copies the imaginary part of GPU data, and
returns a new mxGPUArray object that refers to the copy. The
returned array is real, with element values equal to the imaginary values of the
input, similar to how the MATLAB imag function behaves. If the
input is real rather than complex, the function returns an array of zeros.
