function f = fuz_for(gamma,ua,ub)

% f=fuz_for(gamma,ua,ub)
%
% General OR - Werners[1984].
% ua and ub are the membershipfunctions.
% 'gamma' determines the "maximum-grade" of the operator.(=g)
%
% u(ua,ub) = g*max(ua,ub))+0.5*(1-g)*(ua+ub).           0<g<1. 
%
% For g=1 the operator is identical with the maximum-operator.
% For g=0 the average value is calculated.
