mxGPUCopyImag (C)
Copy imaginary part of mxGPUArray
C Syntax
#include "gpu/mxGPUArray.h" mxGPUArray* mxGPUCopyImag(mxGPUArray const * const mgp)
Arguments
mgp
Pointer to an
mxGPUArray
. The target gpuArray must be full, not sparse.
Returns
Pointer to an mxGPUArray
.
Description
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.
Use mxGPUDestroyGPUArray
to delete the result when you are done with it.
