gpucoder can't see nvToolsExt64_1.lib even if it exist ad it's declared correctly in the environement variable NVTOOLSEXT_PATH.
I tried to disable the firewall obtaining the same problem.
What to do ?
I get error:
Error using gpucoder.profile (line 41)
Unable to find NVTX library 'nvToolsExt64_1.lib'. Ensure that the NVTX SDK installation contains the
specified library file.
when I type :
cfg = coder.gpuConfig('exe');
cfg.GpuConfig.MallocMode = 'discrete';
gpucoder.profile('myH_MEX',ARGS{1},'CodegenConfig',cfg,...
'CodegenArguments','-d profilingdir','Threshold',0.001);

coder.checkGpuInstall by default does not do any profiling checks. To perform these checks, you need to set the Profiling property of the coder.gpuEnvConfig object to true before passing the config to coder.checkGpuInstall.
Since your original question was resolved, can you please create a new question or create a technical support ticket for your follow-up question?

The issue was that the NVTOOLSEXT_PATH environment variable was set to the wrong value.
