Have you run mex -setup ?

Answer 1

VC 2017 certainly won't be recognized by MATLAB R2015a. But SDK 7.1 should be supported. Make sure you have NET Framework 4.0.

Follow link on this page to find the exact detail.

You need to download and install a compiler first.

Go to the add-ons and click on get add-ons. You will get a list of add-ons which you can install.

Install MinGW-w64 GCC from the list and then run the mex setup.

Hope this helps.

you mean this add-ons in the Environment section?

There is no add-ons in Enviroment section in Matlab 2015a. But there is an add-ons in the resources section.

 However, i can not open the add-ons explorer with it. 

[Shounak Shastri]

Sorry this Min64 compiler is for 2015b and above. You probably need .NET framework.

[NNL]

thank you so much. .NET framework is also installed and updated. But it does not work.
