A5 = parallel.gpu.GPUArray.rand(3000,3000);
but I get the following error:
Undefined variable "parallel" or class "parallel.gpu.GPUArray.rand". I don't know why I get this error. I am using Matlab 2015b. Could someone help me?

Do you have the Parallel Processing Toolbox installed and licensed? Check this by the ver command.

That's the old syntax from R2011a or so. In R2015b, you can do simply:
A5 = rand(3000, 3000, 'gpuArray');
(The direct equivalent is gpuArray.rand(3000,3000)).

Both of these create the array directly on the GPU.
