Does MEX acceleration for Deep Learning need a GPU Coder license?

I see the following error message:

coder.checkGpuInstall
Compatible GPU : PASSED
CUDA Environment : PASSED
Runtime : PASSED
cuFFT : PASSED
cuSOLVER : PASSED
cuBLAS : PASSED
cuDNN Environment : PASSED
Error using coder.checkGpuInstall (line 32)
Undefined variable "coder" or class "coder.gpuConfig".
"The 
‘mex’
 option is only available when you are using a GPU. You must also have a C/C++ compiler installed. For setup instructions, see MEX Setup (GPU Coder).

‘mex’ acceleration does not support all layers. For a list of supported layers, see Supported Layers (GPU Coder)."Does MEX acceleration for Deep Learning need a GPU Coder license?
