Standard function poly2mask (and others!) not found even though its directory is in path

After evaluating MATLAB under windows I installed R2010b under OS-X Snow Leopard.

A simple program which runs fine under the Windows MATLAB says

"Undefined function or method 'poly2mask' for input arguments of type 'double'."

when the program is run on the Apple Mac MATLAB.

I checked, and the directory containing poly2mask.m IS in the path (the directory is "/Applications/MATLAB_R2010b.app/toolbox/images/images".

What am I missing?

Is the image processing toolbox licensed for your system?

Also, try giving the command line prompt,

rehash toolbox; rehash toolboxcache
