I think every thing is ok but the answer is not correct
I=imread('C:\Users\AliReza\Desktop\B.jpg');
for Channel = 1 : 3
I1 = I(:,:,Channel);
S=2 ;
[M , N]=size(I1);
M2=S*M;
N2=S*N;
I2=zeros(M2 , N2);
for i =1:M2
for j = 1:N2
x =i/S;
y=j/S;
x2=round(x);
y2=round(y);
if (x2<1)||(x2>M)||(y2<1)||(y2>N)
I2(i , j)=0;
else
I2(i,j)=I1(x2 ,y2);
end
end
I3(:, :, Channel) = I2;
end
imshow(I3,[])

What do you think is incorrect? Why do you think there is a problem? Perhaps you need to either learn to use the debugger, or you need to give more information if you seriously expect an answer.

Not sure what "is not correct" means. Perhaps you'd like to see the Mathworks demo on zooming an image, attached.
Or perhaps you want to use imresize() or imcrop().

Looks like you've accepted Walter's answer so I assume you're all set now. Write back if that's not the case.
