Gaussian combination membership function
y = gauss2mf(x,[sig1 c1 sig2 c2])
The Gaussian function depends on two parameters sig and c as given by
The function gauss2mf is a combination of two of these two parameters. 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] . |
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');
