accumulu.m

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

function B = accumulu(B,accop)

% B = accumulu(B,accop)
% 
% "Accumulation" of all fuzzy conclusions Bj* to one B*. 
% B*=accop(B1*,B2*,...,Bj*,...,Bm*). 
% The operator accop can be a OR-operator. Another method is to sum up all
% the outputs (Kosko 1992). This can be done using 'sumop' for accop.
