Location required for mex files?

I am using a toolkit downloaded from the File Exchange. It calls for using mex to compile some .c files for speed. There are also .m versions of these same files. If one of these compiled functions is called from a .m file in the same directory as the .mex files, the .mex files are used and the speed is excellent. But if the .m file is located elsewhere instead the uncompiled (i.e. .m version) is used and the speed is bad. All files in question are in the path. Is there something else that can be done so the .mex files will be used?

If you can ensure that the mex file is towards the beginning of the path string it will override the m files, see http://www.mathworks.com/help/techdoc/matlab_prog/f7-58170.html

My advice would be to put the mex files in the same directory as the same-named m-file. That way the mex file will always be called to execute the function, but the m-file can still be used for help text.
