Please show the output of

mex -v -setup C

Did you try again after installing the compiler it suggested? If not, why not?

Error using mex

No supported compiler or SDK was found. You can install the freely available MinGW-w64 C/C++

compiler; see Install MinGW-w64 Compiler. For more options, visit

[Qiaoli Ji]

Yes, of course, I have tried and run mex -setup. Errors still existed.

[Walter Roberson]

Well it certainly appears that MATLAB cannot find any trace of any compiler you installed. What compiler have you installed, exactly?

[Qiaoli Ji]

I have installed MinGW-w64 C/C++ complier according to the below link.

So even when following the instruction in the linked bug report you still had no success?

[Qiaoli Ji]

Yes, it is so hard to explain. I saw the last step and present installation complete.

But, i have downloaded a tdm64-gcc-4.9.2.exe and installed it.

When I run mex -setup, it happend as the video showed. So does it work?

[Walter Roberson]

Yes, installation of the compiler was successful.

[Qiaoli Ji]

ok, thanks a lot.
