mgp

Pointer to anmxArray.

Returns

inttype.

Description

mxGPUIsValidGPUDataindicates if the mxArray is a pointer to valid GPU data

If the GPU device is reinitialized in MATLAB withgpuDevice, 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.
