If you have downloaded an M-file, then you need to add the folder (directory) in which that M-file lives to the MATLAB path, otherwise MATLAB cannot find it.

use the addpath() command, or pathtool

For example, if the file is located in c:\mfiles

 >>addpath('c:\mfiles')

Or just enter:

>>pathtool

and add the folder.
