Hi, are you looking to create the same image, or similar pixel based images? You might need to enter the values in matrix manually, as pointed by KSSV.

I can enter the values manually. Similar pixel based image example should work for me.

m = 15; n = 15;
[X,Y] = meshgrid(1:m,1:n) ;
Z = 255*ones(m,n) ;
idx = randperm(m*n,100) ;
Z(idx) = 0 ;
% pcolor(X,Y,Z)
imshow(Z)
grid on
