@DAD: Some suggestions to improve your question:
1. Using a heap of dots decreases the readability.
2. "image with values full of 1,2,3 and 4" is not a unique description of the input data. If you post the Matlab source to create a small example, the readers would exactly know, what you are talking about. Especially the type and dimensions of the inputs are important.
3. "as soon as possible"?! It is sunday and it is my spare time.

Have you considered rgb2ind() ?

You mean like this:
% Generate some sample data in the range 1-4.
m = randi(4, [50 50]);
% Display the image.
imshow(m, []);
% Set up a colormap.
cmap = [1 0 0; ... % 1 = Red
0 0 1; ... % 2 = Blue
0 1 0; ... % 3 = Green
1 1 0]; % 4 = Yellow.
% Apply the colormap.
colormap(cmap);
colorbar();
% Enlarge figure to full screen.
set(gca, 'units','normalized','outerposition',[0 0 .9 .9]);
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
set(gcf,'name','Demo by ImageAnalyst','numbertitle','off')
