how to use GPU to speed up the execution of Matlab algorithms ?

I did simulations on MATLAB which takes a lot of time so I found that GPU is the effective solutions to reduce the calculation time but the problem I do not know how to use GPU on MATLAB despite having an NVIDIA card

The documentation is the best place to start, but you will need the Parallel Processing Toolbox.

See https://www.mathworks.com/products/matlab/choosing_hardware.html#_Graphics_Processing_Unit_1:

 To speed up computation, Parallel Computing Toolbox leverages NVIDIA GPUs
 with compute capability 2.0 or higher. See the compute capabilities of all
 NVIDIA GPUs. MATLAB does not support computation acceleration using AMD or
 Intel GPUs at this time.

This means that installing an NVIDIA card is obligatory.

yes I have Parallel Processing Toolbox because I use MATLAB 2016a and I have NVIDIA cart but the problem when I start for example this code :

x=rand(10,'single');
G=gpuArray(x);
isequal(gather(G),x)
classUnderlying(G)
G2=G.*G

the following message shown:

can't reload 'C:\Program Files\Matlab\R2016a\bin\win64\gpu.dll

You might need to reinstall the Parallel Processing Toolbox.

... Especially if you happened to be on a Dell: Dell's backup and recover process used to cause problems like this.

I can't understand this but I have not Dell's backup and recovery
