dsigmf - Built-in membership function composed of difference between two sigmoidal membership functions

Syntax

y = dsigmf(x,[a1 c1 a2 c2])

Description

The sigmoidal membership function used depends on the two parameters a and c and is given by

The membership function dsigmf depends on four parameters, a1, c1, a2, and c2, and is the difference between two of these sigmoidal functions.

f₁(x; a₁, c₁) - f₂(x; a₂, c₂)

The parameters are listed in the order: [a₁ c₁a₂ c₂].

Examples

x=0:0.1:10;
y=dsigmf(x,[5 2 5 7]);
plot(x,y)
xlabel('dsigmf, P=[5 2 5 7]')
