c++ and matlab functions equivalent

correct me if i'm wrong.. as i just started learning how to use c++ and matlab, there is a matter i confused. i know that to call c++ code from matlab i have to replace my main() to mexFunction(). i've done that..here i want to know is that functions like mexprintf and soon must be used instead of cout(c++) in other source files? and is it the functions like mexprintf, mexCALLMATLAB etc only used inside mexFunction?

Hi,

yes and yes. See at the bottom here for the cout question

http://www.mathworks.com/help/matlab/matlab_external/c-c-source-mex-files.html

and for the mexPrintf and mexCallMATLAB: Those functions are definied in the mex.h and work only inside a MEX file.

@Khairul: To clarify, all of the mex API functions can be used anywhere in your mex code. You don't have to call them from inside the mexFunction itself.
