That does not make any sense at all. A logical/binary image is already at maximum contrast and does not need histogram equalization. If you did it, it would simply return the same image. Even if you ran histeq() on a gray scale image, that's even useless most of the time, though some people like to do it unnecessarily because they don't know any better. adapthisteq() can be useful to flatten out uneven background illumination, though it doesn't make sense for a logical image.
