This will convert a maple expression into a string as a matlab expression
with(StringTools):
MATLAB := (s) -> SubstituteAll(SubstituteAll(SubstituteAll(SubstituteAll(convert(simplify(s,size),string),"*",".*"),"^",".^"),"/","./"),"Pi","pi"):
As in
MATLAB(x*y^z/w);
will output:
"x.*y.^z./w"
It'd be cool to get rid of the "
at the beginning and end, too.
