Hi everyone!
I have an array A,
A = [ 1 2 3 4
2 2 3 1
1 1 4 2];
I want to create a colormap but each element needs to be colored in a specific colour, for example, 1 is blue, 2 is black, 3 is green and 4 is yellow.
Thanks

Given these data, I would do this.
A = [ 1 2 3 4
2 2 3 1
1 1 4 2];
cmap = jet(max(A(:)));
figure;
imagesc(A);
colormap(cmap);
colorbar;
