I want to creat a black image with white circular spots on it, where I can edit the size of the spots.

zeros() would create the black image for you. You would then use one of the techniques for creating circles that you would set to 1 (white).
Alternately you could use insertShape from Computer Vision Toolbox.

Or you could call "hold on" and call plot() then call exportgraphics() to save the image with spot on it to disk.
