I have a few matrices containing different integers, and I know all the possible intergers which can be found within these matrices. But not every integer will appear in each matrices, like:
% possible integers 0 1 2 3
x = randi([0 3],10,10); % from 0 to 3
y = randi([0 2],10,10); % from 0 to 2
z = randi([0 1],10,10); % from 0 to 1
Then how can I fix the mapping between matrix integers and RGB colors so that specific integer is always associated with specific color( as commented ) ?
cmap= [0 0 1;... % blue for 0
0 1 0;... % green for 1
1 0 0;... % red for 2
1 1 1]; % white for 3
figure;
imagesc(x);
colormap(cmap);
figure;
imagesc(y);
colormap(cmap);
figure;
imagesc(z);
colormap(cmap);
