r = rand(20, 30);
g = rand(20, 30);
b = rand(20, 30);
rgb = cat(3, r, g, b);

hi jan, r = rand(20, 30); g = rand(20, 30); b = rand(20, 30); rgb = [r, g, b]; imshow(rgb)
thats my code.. could you explain me whats the different between your code and mine. I am getting gray image as output. But,you are getting colored one. could you explain this technically. why i am not getting color image even though i concatenated those three basic colors.

If you get pure gray it might be because your R G and B images are identical or close to identical?

[r,g,b] is equivalent to cat(2, r, g, b): It concatenates along the 2nd dimension. Try it with smaller values to keep the overview:
r=[1,2;3,4]; g=r+5; b=g+5;
disp([r,g,b])
disp(cat(3, r, g, b))
The concatenation along the 2nd dimension creates a 2D matrix of type double, which is displayed as grey scale image.
