I have a 2D boolean array stored 0s and 1s where I want to plot a red pixel. For example, If the 2D boolean array has 1 for (20, 20) location, it should plot a red pixel at that location. Else, it is has 0, it should not plot the red pixel.
Can someone help me?

% your array
A = randi(2,101)-1;
% the result;
R=255*ones(101);
G=255*(-A+1);
B=255*(-A+1);
res = cat(3,R,G,B);
% plot result
imshow(res)

On File Exchange there are also tools to create gif animations. Maybe you want to use this.
