Recursive Directory Function Execution

Recurses through each directory, passing the full directory path and any extraneous arguments (varargin) to the specified function.

Call Sequence : directoryRecurse(directory, function_pointer, varargin)

IE: To execute the 'rmdir' command with the 's' parameter over 'c:\tmp' and all subdirectories:

directoryRecurse('c:\tmp', @rmdir, 's');

Another useful example, add 'c:\matlab' and all sub directories to the Matlab path:
directoryRecurse('c:\tmp', @addpath);
