ctr_func.m

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

function  [y,x] = ctr_func(ctr,ts,bo)

% [y,x] = ctr_func(ctr,ts,bo)
%
% Input - Output function of a one-dimensional fuzzy or neural controller.
%
% ctr is the name of the controller-file. (given as a string)
% bo = [from to] = the range to be calculated.
% ts = sampling time - passed to the controller.
% The controller file gets besides the input value a state vector with the
% input and output values from the last sample step.
%
% Without lefthand arguments the function is plotted.
