gamma_b.m

FISMAT accommodates different arithmetic operators, fuzzification and defuzzification algorithm, imp

function f=gamma_b(gamma,ua,ub)

% f=gamma_b(gamma,ua,ub)
%
% GAMMA operator 
% Convexcombination of T-norms with the corresponding
% S-norms:
% Here convexcombination of Minimum- and Maximum- operator.
% This operator is not associative.
% gamma=0 => maximum-operator    gamma=1 => minimum-operator
