I already have MinGW-w64 on my computer. If I install the MinGW-w64 compiler from Add-Ons on MATLAB, do these two interfer with each other?

You can test the MinGW® compiler by building the yprime.c example. Copy the source file to a writable folder.
copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'),'.','f')
If you only have the MinGW compiler installed on your system, the mex command automatically chooses MinGW. Go to the next step. However, if you have multiple C or C++ compilers, use mex -setup to choose MinGW.
mex -setup
Build the MEX file.
mex yprime.c
MATLAB displays a “Building with” message showing what compiler was used to build the MEX file.
Run the function.
yprime(1,1:4)
For more information, see Troubleshooting and Limitations Compiling C/C++ MEX Files with MinGW-w64.

Thank you for your reply.
When I tried
mex -setup
only with MinGW on my computer, I got error saying MATLAB could not find any compiler.(Sorry actual error was japanese.)
There might be some problems with my paths though.
I found answers recomending download of MATLAB function 'configuremingw' but I did not understand where it was attached.
And, just for information, of course MinGW from Add-Ons on MATLAB enabled me building the mex file.
I put the mingw under 'C: without any space but failed. But I might find helpfull hints from the link you mentioned, so I'll check it more carefully.
Thank you!!
