Sir i A Santosh Kumar working with Back propagation algorithm could not get the requried output for the matlab code which i have written please correct me in this context so that i can get the output which is shown below

 clc();
v=[0.197 0.3191 -0.1488 0.3394;0.3099 0.1904 -0.0347 -0.4861];

b1=[-0.3378 0.27781 0.2859 -0.3329];
b2=-0.1401;

w1=zeros(4,1);

epoch=0;
while con>0
    e=0;
     for I=1:4
for j=1:4
    zin=b1;
        for i=1:2
        zin(j)=zin(j)+x(i,I)*v(i,j);
    end
z(j)=1/(1+exp(-zin(j)));
end
 z;
 for i=1:4
     yin=b2+z*w;
 end
 yin;
 y(I)=1/(1+exp(-yin));
 for I=1:4
 deltak=(t(I)-y(I))*y(I);
 end
 deltaw=alpha*deltak*z(j)+mf*(w-w1);
deltab2=alpha*deltak;
deltainj=deltak*w;
for j=1:4
    deltaj(j,1)=deltainj(j,1)*z(j);
end
for j=1:4
    for i=1:2
        deltav(i,j)=alpha*deltaj(j,1)*x(i,I)+mf*(v(i,j)-v1(i,j));
    end
end
deltav;
 deltab1=alpha*deltaj;
 w1=w;
 v1=v;
 w=w+deltaw;
 b2=b2+deltab2;
 v=v+deltav;
 b1=b1+deltab1';
 e=e+(t(I)-y(I))^2;
 end
 con=con-1
 epoch=epoch+1;
end
disp('BPN for XOR function with binary input and output');
disp('Final Weight Matrix and Bias');
e

 b2
the output for the above program is

BPN for XOR function with binary input and output Final Weight Matrix and Bias

e =

3.0892e-004

v =

    1.9700    3.1910   -1.4880    3.3940
    3.0990    1.9040   -0.3470   -4.8610

b1 =

   -0.9359    0.9811    0.7207   -0.5950

w =

    2.9807
   -3.8513
   -4.9173
    2.6427

b2 =

   -0.3955
which is wrong.
The expected out put is
Output

Any particular reason anyone should do your work? I would recommend you learn to use the debugger, go through your code line by line and try to locate the errors yourself. People in this forum are more than willing to help but please show some effort on your part.
