documentation is
   "This style highlights function definitions and a limited"
   "number of keywords, mostly control constructs, and is"
   "therefore usable for many Matlab versions. Special care" 
   "have been taken to distinguish string delimiters from the" 
   "transpose operator (which is the same symbol) and to"
   "recognize comments."
