I was trying to learnt the libSVM on MATLAB, it is giving this error? Can any body please guide me how to add compiler on MATLAB
Error: D:\PhD\MATLAB\libsvm-3.24\libsvm-3.24\matlab\make.m failed (line 13)
No supported compiler or SDK was found. You can install the freely available MinGW-w64 C/C++ compiler;
Thanks

You may search for "MATLAB Support for the MinGW-w64 C/C++ Compiler" in the MATLAB Add-ons menu. You can then install the support package from the Add-on explorer.
More information on accessing the Add-ons menu can be found in the following link:

@ Chidvi Modala Sir,
Thankyou Sir, for your reply and it is working but in the next step it is giving another problem which is:
"
>> make
Building with 'MinGW64 Compiler (C)'.
Error: C:\Users\Ht\MATLAB\libsvm-3.24\matlab\make.m failed (line 13)
gcc: error: \-fexceptions: No such file or directory
=> Please check README for detailed instructions.
=> Please check README for detailed instructions."
Please guide me. Thankyou

This error may be due to a corrupt installation of the MinGW compiler.
To solve this issue, please re-install MinGW:
https://in.mathworks.com/help/matlab/matlab_external/install-mingw-support-package.html
and then set it as compiler from the MATLAB Command Window:
>> mex -setup
You should then be able to build a mex file:

To build a C MEX S-function instead, you can try with timestwo.c at the following link:
https://uk.mathworks.com/help/simulink/sfg/s-function-examples.html#f6-18765
If the issue is not solved, there may be incompatibilities with other compilers that have the same command gcc (for instance, GFortran and EGCS).
Removing those compilers should solve the issue.
