I could probably make a wizard just for Matlab mex functions?
It's not as easy as you may think - you will have to take a lot into account. There are at least 3 different Matlab versions (in terms of MEX files) that require different settings which itself depend on the compiler. In addition the language matters - you can have Fortran, C and C++ MEX functions. BTW: the mexw32 extension is rather new so this would break any old Matlab version - so be careful with this.
BUT: I am working on that, too already. It's not yet perfect but it's btw the most complex wizard I've ever done. ;-) Any yes: It *has* to be a different wizard than the DLL one.
So, feel free to contribute, I would merge our work then before release.
Hence I wouldn't commit such into SVN unless we have added support for LCC which is the default compiler for Matlab. Everything else would be just too confusing for Matlab newbies IMHO... That's at least my experience form work.
