i write this one for gray image but i looking for rgb's too (nearest neighbor)
I1=[50 80 100 ; 115 21 90 ;32 50 160];
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
end

for Channel = 1 : 3
I1 = YourImage(:,:,Channel)
now do the zooming here, just like above except without the assignment to I1
I3(:, :, Channel) = I2;
end

Your very first line was
I1=[50 80 100 ; 115 21 90 ;32 50 160];
Omit that line completely. Instead, before the loop, initialize YourImage to be an appropriate RGB image.
