I'm working on an example where I'm getting a logical error possibly. I want to replace every element of a matrix by the minimum of its neighborhood.

I've written the following piece of code. But it's not running and giving an error which I'm unable to figure out.
z = rgb2gray(imread('gantrycrane.png')); figure, imshow(z)
for i = 2:263
N = 0;
for j = 2:399
for k = (i-1)+N:(i+1)+N
for l = j-1:j+1
if(z(k,l)>z(i,j))
z(i,j)=z(k,l);
end
end
end
N = N+1;
end
end

The value of N will be very large in the loop and gives an error.
Try the following to replace each element of the matrix by by the minimum value of its neighborhood (including the element itself).
for r = 2:263
for c = 2:399
region = z(r-1:r+1,c-1:c+1); % Extract the neighborhood for each element
z(r,c) = min(min(region));
end
end
