The mage has 50 x 100 points (vertical x horizontal dimension). Each point can be zero or one, where zero = white colour and one = black colour.
I tried this
B = randi([0 1],50, 100);
imagesc(B)
The output image is represented with yellow and blue but I want it to be black and white.

You don't need a colormap. Just try this:
B = randi([0 1],50, 100);
imshow(B)
impixelinfo();
