Calling a C function from a .m file

I'm trying to make a Matlab function that will call a C function and send and receive data from that C function. Basically I'm looking for the equivalent of MexCallMATLAB to write in a .m file.
All help is appreciated.

If you own MATLAB Coder (R2011a) or Real-Time Workshop (R2010b or earlier), you can use coder.ceval (MATLAB Coder) or eml.ceval (Real-Time Workshop), and then automatically generate a MEX-Function from the MATLAB code.

Would that be appropriate for the case where someone has an existing C function that they want to call from MATLAB ?

Yes. Please see the following example:

calllib() might be the closest to that. Sometimes, though, it is easier to write an MEX interface to the routine.
