I am trying enlarge an image using interpolation without using MATLAB commands, but my image isn't resizing properly.

This function interpolates the rows first and then the columns from the interpolated rows.
function [enl] = enlarge(image)
img = imread(image);
img = double(img);
[m,n] = size(img);
% enl = zeros(m,n);
for i = 1:1:m
for j = 1:2:n-1
enl(i,j+1) = (img(i,j)+img(i,j+1))/2;
end
end
for i = 1:2:m-1
for j = 1:1:n
enl(i+1,j) = (img(i,j)+img(i+1,j))/2;
end
end
imshow(enl)
imwrite(enl, 'enl.gif')
end

Please describe the difference between what you see and what you want.

You are interpolating in one direction, but then you are ignoring the results of that when you interpolate in the other direction. Both times you overwrite the matrix en1 with values computed solely from img.

It doesn't say that. "unusage" is not even a word. Paste the actual error message, including the line of code and the line numbers and the actual error message, as well as your script. In other words, attach your script, and any image or data that needs to be read in by it, and paste back here the complete error message ( ALL the red text).
