trapmf - Trapezoidal-shaped built-in membership function
Syntax
y = trapmf(x,[a b c d])
Description
The trapezoidal curve is a function of a vector, x,
and depends on four scalar parameters a, b, c,
and d, as given by
or, more compactly, by
The parameters a and d locate
the "feet" of the trapezoid and the parameters b and c locate
the "shoulders."
Examples
x=0:0.1:10;
y=trapmf(x,[1 5 7 8]);
plot(x,y)
xlabel('trapmf, P=[1 5 7 8]')
