I am mystified by this problem. Rush doesn't seem to work for me,  
even though I think I am following the instructions correctly. Here  
is an excerpt from the command line:  
  

> \>\> a={'clock'};  
>    
> \>\> class(a)

ans =  
cell  
  

> \>\> Rush(a)

Error in function : Usage error  
First input argument must be either a cell array or a string.  
??? Usage:  
(null)  

> \>\>

Am I overlooking something simple?   
Thanks for your help.
