trimf

Triangular-shaped built-in membership function

Syntax

y = trimf(x,params)
y = trimf(x,[a b c])

The triangular curve is a function of a vector, x, and depends on three scalar parameters a, b, and c, as given by

or, more compactly, by

The parameters a and c locate the "feet" of the triangle and the parameter c locates the peak.

x=0:0.1:10;
y=trimf(x,[3 6 8]);
plot(x,y)
xlabel('trimf, P=[3 6 8]')
