wait (GPUDevice)
Wait for GPU calculation to complete
Syntax
wait(gpudev)
Description
wait(gpudev) blocks execution in MATLAB until the GPU device identified by the
GPUDevice object gpudev completes its calculations. This can be used before calls to
toc when timing GPU code that does not gather results back to the workspace. When
gathering results from a GPU, MATLAB automatically waits until all GPU calculations
are complete, so you do not need to explicitly call wait in that situation.
