This is not how to make an engine application. You need to use a bat file from the appropriate directory. e.g., for MSVC you might do this to compile a single file MyProc.cpp into a MyProc.exe executable:

options = [matlabroot '\bin\win32\mexopts\msvc80engmatopts.bat'];
mex('-f', options, '-v', 'MyProc.cpp');

Then run it like this:

!MyProc

If you have more than one source file then just string them out as additional arguments in the mex command. e.g.,

mex('-f', options, '-v', 'file1.cpp', 'file2.cpp', 'file3.cpp');

By default, the executable name will be taken from the first cpp file in the list.

Thank you so much James
I've gottn it now
thanks to ur last two posts
I created an executable MyProc.exe (with mex('-f',options,'-v','all my cpp files') ) that reads user supplied input tolerance values from a file user_input.txt and the calls the matlab engine using engCallMatlab to execute the user-defined function user_function.m
I then made a GUI Gui.exe (built from Gui.m and Gui.fig) that simply creates the user_input.txt and then calls MyProc.exe
I can now package my application with just MyProc.exe and Gui.exe; and all the user need do is write user_function.m
I'm so happy!!
Thanks
