Hello,

Please,this is my program and I want to plot separating line for

my array but the problem that only one figure appeared in my

program and I must draw four figure not only one for the array,so

what is the problem?? please help me

clear all;

clc;

disp('Hebb network for XOR function Bipolar inputs and targets');

%input pattern

x1=[1 1 -1 -1];

x2=[1 -1 1 -1];

%bias input

x3=[1 1 1 1];

%target vector

t=[-1 1 1 -1];

%initial weights and bias

w1=0;w2=0;b=0;

for i=1:4

    delw1=x1(i)*t(i);
    delw2=x2(i)*t(i);
    delb=x3(i)*t(i);
    %weight change
    wc=[delw1 delw2 delb];
    %updating of weights
    w1=w1+delw1;
    w2=w2+delw2;
    b=b+delb;
    %new weights
    w=[w1 w2 b];
    disp(w);
    m=(-x1*(w1(i)/w2(i)))-(b(i)/w2(i));
    plot(m);
end
