When I run the following code statement: model = svmtrain(labels, data, '-s 0 -t 2 -c 1 -g 0.1');
I get error: Invalid MEX-file 'C:\Program Files\libsvm-3.21\windows\svmtrain.mexw64': The specified procedure could not be found.
I tried all the ways to fix it, set the folder to matlab path, but couldn't understand where the problem is.
Please advise.

svmtrain.mexw64 needs a DLL that you do not have (or which cannot be found.)
You should either use a tool such as Dependency Walker to track down the missing DLL, or else you should use the Statistics toolbox with R2013b or later, which has SVM built in.

I used Dependency Walker previously and installed all the missing DLL files, but error is still there.
I am not able to get what the issue is. Please advise.

Sorry, I do not have a compiler set up on my Windows virtual machines, so I cannot build libsvm.
