gauss2mf

Gaussian combination membership function.

Synopsis

y = gauss2mf(x,[sig1 c1 sig2 c2])

Description

The Gaussian function depends on two parameters sig and c as given by

The function gauss2mf is a combination of two of these. The first function, specified by sig1 and c1, determines the shape of the leftmost curve. The second function specified by sig2 and c2 determines the shape of the right-most curve. Whenever c1 < c2, the gauss2mf function reaches a maximum value of 1. Otherwise, the maximum value is less than one. The parameters are listed in the order:

[sig1, c1, sig2, c2].

Examples

x = (0:0.1:10)';
        y1 = gauss2mf(x, [2 4 1 8]);
        y2 = gauss2mf(x, [2 5 1 7]);
        y3 = gauss2mf(x, [2 6 1 6]);
        y4 = gauss2mf(x, [2 7 1 5]);
        y5 = gauss2mf(x, [2 8 1 4]);
        plot(x, [y1 y2 y3 y4 y5]);
        set(gcf, 'name', 'gauss2mf', 'numbertitle', 'off');
