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.
