Can I call an external shared library (DLL) from a MATLAB MEX-file?

I would like to call an external shared library (DLL) from a MATLAB MEX-file.

To link an external DLL to a MEX-file, list the DLL's .lib file on the command line.

Here is an example:

mex filename.c libname.lib

Note that when calling the MEX-file from MATLAB, the DLL should be in the same directory as the MEX-file.

You call functions from the lib file just like you would call any other function in your code. As long as the function is exported in the lib file, and you have included the appropriate prototypes in your source code (e.g. via a header file), there is nothing else special you need to do. LoadLibrary has nothing to do with this.

The link to f13120 is obsolete.

@Walter I removed it. Thanks!
