Below is the content with the final error of the log file from the GPU coder in Matlab.
Could someone help me in letting me know why nvcc cannot find -lcublas as written at the end of the log file?

Hi,
I understand that you are facing an issue while using GPU Coder.
The error is possibly occurring because “cuBLAS” was not installed on your system or it was not installed in the default path.
% Default path
'/usr/local'
To check whether cuBLAS is installed on your system, please look for the “include” folder containing cublas.h. The path should be as follows
% include path
'/usr/local/cuda/include/cublas.h'
% If CUDA Toolkit was installed in 'path_to_cuda_root'
'<path_to_cuda_root>/cuda/include/cublas.h'
The issue you are facing can be resolved by reinstalling the NVIDIA HPC SDK or CUDA Toolkit.
For more information refer the following documentation
  1. https://www.mathworks.com/help/gpucoder/ref/gpucoder.html
  2. https:/www.mathworks.com/help/gpucoder/ref/gpucodersetup-app.html
  3. https://developer.nvidia.com/cublas
Hope this is helpful.
