Good idea, thanks.

The default aurgument for script is " -e ''" (the perl interpreter  
executes an empty statement and exits). But I didn'd succeed in  
setting a deault argument for varargin (syntax error at least in  
version 3.0.0).

The type (iscellstr) is performed, but still empty command line  
argument strings are allowed. The argument script needs to be  
nonempty and a string.
