Determine if mxArray is pointer to valid GPU data
#include "gpu/mxGPUArray.h" int mxGPUIsValidGPUData(mxArray const * const mp)
mgpPointer to an mxArray.
int type.
mxGPUIsValidGPUData indicates if the mxArray
is a pointer to valid GPU data
If the GPU device is reinitialized in MATLAB with gpuDevice, all data on the device becomes
invalid, but the CPU data structures that refer to the GPU data still
exist. This function checks whether the mxArray is a container of
valid GPU data, and returns one of the following values:
0 (false) for CPU data or for invalid GPU data.
1 (true) for valid GPU data.
