I have the following matrix A = [-1 1 1; 1 -1 1; -1 -1 -1], I want to convert it to a colored matrix with cells corresponding to 1 colored red and -1 colored blue. Something like this:
How do I do that in matlab?

A = [-1 1 1; 1 -1 1; -1 -1 -1]
A = 3×3
-1 1 1 1 -1 1 -1 -1 -1
imagesc(A);
% select a colormap
cmap = hsv(8); % based on hsv
cmap = cmap([5 1], :); % choose color 5 and 1
colormap(cmap);
colorbar
