Seems pretty clear from the very first message:
Warning: Selected MEX compiler 'MinGW64 Compiler (C++)' is not supported for GPU code generation. Refer to the
GPU Coder documentation for a list of supported GPU MEX compilers.

You need Visual Studio to compile for GPU Coder

The problem is fixed for me when I installed gcc 6.5.0.

gcc can only be used for GPU Coder on Linux, not on Windows; for Windows you must have Visual Studios.

I installed Visual studios 2019 and I am getting the error
Error using dlquantization.instrument
The value of 'executionEnvironment' is invalid. No GPU available. dlquantizer requires a GPU machine to quantize a network object.
Error in dlquantizer/calibrate (line 25)
results = dlquantization.instrument(obj.NetworkObject, p.Results.data, obj.DLAccelData, 'BatchSize', p.Results.batchSize,
'MiniBatchSize', p.Results.miniBatchSize, 'ExecutionEnvironment', obj.ExecutionEnvironment);

ikeuwanuakwa : do you have a supported NVIDIA GPU ? The supported execution environments for that function are only GPU or FPGA.

First download visuaal studio 2019 with sdk applications and write mex -setup to command window and then choose vs 2019 and c++.

https://visualstudio.microsoft.com/vs/older-downloads/ . It looks like you will need to log in to download the older releases.

Are you saying that although you created a Microsoft account, Microsoft refused to let you download VS 2019 ?
Are you saying that although you were able to download VS 2019, that your MacOS Sierra system refused to install the product?
Are you saying that you got everything installed seemingly okay, but you still encountered a message "No GPU available" ?

I use windows 10 and I have lenovo ideapad310-15ISK with GPU Geforce 920MX. I installed VS 2019, but I have error. I don't certain about preferencies that I set up.

I had similar problem.
Run gpuDevice from terminal
It poped an error that my nvidia driver is not supported and I have to update it first.
