Can I run Matlab function on multiple GPU?

I work on image processing and handle big array of images. I need to use Matlab function, let, median filter on multiple GPU. I can run on 1 GPU but I have 4 GPUs so I want to run each Matlab function on all 4 GPUs. Is it possible to run every Matlab function in all 4 GPUs instead of just 1 GPU?

No, there is no way to run a user function on multiple GPU at this time.
At this time, each process can use gpuDevice to select a single GPU (this is done automatically for parpool members when the pool is no larger than the number of GPU.) Selecting a second GPU device would reset the first device.
Mathworks is doing work on sharing load between two hardware connected NVIDIA, and has implemented it for one particular kind of deep learning, and for one other task that is not coming to mind at the moment. Unfortunately I am having difficulty finding the appropriate postings.
