mxGPUCopyFromMxArray (C)

Copy mxArray to mxGPUArray

C Syntax

#include "gpu/mxGPUArray.h"

mxGPUArray* mxGPUCopyFromMxArray(mxArray const * const mp)

Arguments

Pointer to an mxArray that contains either GPU or CPU data.

Returns

Pointer to an mxGPUArray.

Description

mxGPUCopyFromMxArray produces a new mxGPUArray object with the same

characteristics as the input mxArray.

• If the input mxArray contains a gpuArray, the output is a new copy of the data on

the GPU.

• If the input mxArray contains numeric or logical CPU data, the output is copied to

the GPU.

Either way, this function always allocates memory on the GPU and allocates a new

mxGPUArray object on the CPU. Use mxGPUDestroyGPUArray to delete the result when

you are done with it.
