plot separating line

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

Insert a figure inside the loop to open a new window:

...
for i=1:4
  figure;
  ...

Thanks Jan for your answer

but when I do that, only one figure appears to me and

I need to display four figures not only one and this is my main

problem,please help me in that.

I do not think that this creates one figure only:

for i=1:4, figure; end

Is the OP after 4 lines in 1 figure? If so, try putting "hold on" after the plot command in the loop.
