%corner has 1 gray scale value(white)
clc
clear all
close all
size=1000;
pic=[];
p=0;q=0;
for m=1:size
for n=1:size
pic(m,n)=sqrt(((m/1000-p)^2+(n/1000-q)^2)/2);  
end
end
imshow(pic)

close all
pic=magic(1000); %It creates a magic square matrix with the range of 1 to 2^n
imagesc(pic) %Scales the image data to the full range of current colormap
colormap(gray(256)) % set the color to gray scale range of 0 to 255
axis equal %Equal axis in both x and y direction
