Create read-only mxGPUArray object from input mxArray
#include "gpu/mxGPUArray.h" mxGPUArray const * mxGPUCreateFromMxArray(mxArray const * const mp)
mpPointer to an mxArray that contains either GPU or
CPU data.
Pointer to a read-only mxGPUArray object.
mxGPUCreateFromMxArray produces a read-only
mxGPUArray object from an mxArray.
If the input mxArray contains a
gpuArray, this function extracts a reference to the
GPU data from an mxArray passed as an input to the
function.
If the input mxArray contains CPU data, the data is
copied to the GPU, but the returned object is still read-only.
If you need a writable copy of the array, use
mxGPUCopyFromMxArray instead.
This function allocates a new mxGPUArray object on the CPU. Use
mxGPUDestroyGPUArray to delete the result when you are done
with it.
