defuzz - Defuzzify membership function
Syntax
out = defuzz(x,mf,type)
Description
defuzz(x,mf,type) returns a defuzzified value out,
of a membership function mf positioned at associated
variable value x, using one of several defuzzification
strategies, according to the argument, type. The
variable type can be one of the following:
centroid: centroid of area
bisector: bisector of area
mom: mean value of maximum
som: smallest (absolute) value
of maximum
lom: largest (absolute) value of
maximum
If type is not one of those listed, Fuzzy Logic Toolbox software
assumes it to be a user-defined function. x and mf are
passed to this function to generate the defuzzified output.
Examples
x = -10:0.1:10;
mf = trapmf(x,[-10 -8 -4 7]);
xx = defuzz(x,mf,'centroid');
