Function inside a function
显示 更早的评论
Hello, I'm having some problem with a function defined in terms of other functions: specificly I'm trying to parse a regular expresion with a CFG. The problem is that one of the functions, don't start where it should.
Is something like this:
function [D cad2]=Prod(cad1)
[D cad2]=Termin(cad1)
if ~isempty(cad2)
while strcmp(cad2(1),'.')
[E cad2]=Termin(cad2);
After I execute Termin, I want that the "function Prod" start in [E cad2]=Termin(cad2); not from the beginning.
Thanks.

You cannot change where a function starts.
Perhaps you want to use "persistent", if you want to save state between calls to "Prod".

You could just recursively call the function Prod.
