function out=newfis(fisName,fisType,andMethod,orMethod,impMethod,aggMethod,defuzzMethod)
%NEWFIS Create new FIS.
%   FIS=NEWFIS(FISNAME) creates a new Mamdani-style FIS structure
%
%   FIS=NEWFIS(FISNAME, FISTYPE) creates a FIS structure for a Mamdani or 
%   Sugeno-style system with the name FISNAME.
%
%   FIS=NEWFIS(FISNAME, FISTYPE, andMethod, orMethod, impMethod, ...
%              aggMethod, defuzzMethod)
%   specifies the methods for AND, OR, implication, aggregation, and 
%   defuzzification, respectively.
