How to put a figure window in the center of the screen?

Is it possible to put a figure (for example a GUI window) in the center of the screen? How to get screen size in pixels, or how to measure position not from the bottom, but from the top?

width = 640; height = 480;
Pix_SS = get(0,'screensize')
Pix_SS = 1×4
1 1 1920 1200
[(Pix_SS(3)-width)/2 (Pix_SS(4)-height)/2 width height]
ans = 1×4
640 360 640 480
figure('Position', [(Pix_SS(3)-width)/2 (Pix_SS(4)-height)/2 width height])

Historically, 0 was used to refer to the "root" of the handle graphics system -- the object that is the parent of all figures (and other figure-like graphics objects.)
These days, using groot is the preferred way to refer to the root of the graphics system. (There are a small number of differences between using 0 and using groot() that most people would never notice)

movegui('center')
or
movegui(fig,'center')
where fig is a figure handle.
