What is the best way to determine if a usable GPU is available?

I have an app that is used by many people in our collaboration some with GPU's and parallel toolbox and some without.
I can't seem to the find the canUseGPU() function that returns true if the parallel toolbox is loaded and a compatible GPU is available to the program.
I know it is probably simple and the problem is I'm probably too simple to find it.
Thanks, Joe

Hi Joe,
There is not presently a function called 'canUseGPU' in Parallel Computing Toolbox. Matt's answer will work. You could also use the function parallel.gpu.GPUDevice.isAvailable instead of gpuArray, e.g.
canUseGPU = parallel.gpu.GPUDevice.isAvailable;
catch ME
canUseGPU = false;

Thanks James,
What I ended up doing was putting try catch around the gpuDevice function and also checking if enough memory is available for my job.
As with most programming problems once you get it it's obvious.
