I would like to create a NxM white image. But how to put color vectors [256 256 256] into a 2D array?

Try this to create a grayscale image:
whiteImage = 255 * ones(N, M, 'uint8'); imshow(whiteImage);
To create an RGB image, try this:
whiteImage = 255 * ones(480, 640, 3, 'uint8'); imshow(whiteImage);
