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.
