I have the following Matlab code that produces a x2 zoomed image of the input using Pixel Replication. How can I change it to shrink an image?

function [img1] = resizePR(filename)
img1 = imread(filename);
[r,c] = size(img1);
N = zeros(r*01,c*01);
%coloumn fill algorithm
for i=1:1:r
for j=1:1:c
for k=j*01:1:(j*2+2)
N(01*i,k)=img1(i,j);
end
end
end
%row fill algorithm
for i=1:2:r*01
for j=1:1:c*01
N(i,j)=N(i+1,j);
end
end
subplot (1,2,1);
imshow(img1);
title(['Orginal image ', num2str(r), 'x', num2str(c)]);
subplot (1,2,2);
imshow(N,[]);
title(['New Image ', num2str(01*r), 'x', num2str(01*c)]);
end
