Is there a way to show the binary matrix b as points (say using scatter or a similar command) so I can see individual 1 and 0 values corresponding to different rows and columns with different colors for 0s and 1s similar to imagesc?
For instance the following script generates
a=rand(6,5);
b = a > 0.5;
% b is generated as follows
% 1 1 0 0 0
% 1 0 0 0 1
% 1 1 1 0 1
% 0 1 0 1 0
% 0 1 1 1 1
% 0 0 0 1 0
%replace the following so on the plot
% corresponding to (i,j) I can see a yellow "x" representing 1
% or a red "x" representing 0.
imagesc(b);colorbar;
