psigmf - Built-in membership function composed of product of two sigmoidally shaped membership functions
Syntax
y = psigmf(x,[a1 c1 a2 c2])
Description
The sigmoid curve plotted for the vector x depends
on two parameters a and c as
given by
psigmf is simply the product of two such
curves plotted for the values of the vector x
| f1(x; a1, c1)
× f2(x; a2, c2) |
The parameters are listed in the order [a1 c1 a2 c2].
Examples
x=0:0.1:10;
y=psigmf(x,[2 3 -5 8]);
plot(x,y)
xlabel('psigmf, P=[2 3 -5 8]')
