I'm new to MATLAB and I want to consider a 4x4 pixel block with it's intensities from a whole picture which is a grey scale image. How do I do it?

a = imread('Spiderman.png');
y = rgb2gray(a);
for i = 186:1:189
for j = 165:1:168
pixel_values = y(i,j);
end
end
I wrote this code. I think I made a mistake because it's not working. I hope you can help me with it. Thank you.
