Sets the proportion of height over width (the aspect ratio)
for the current window, where ratio
is an integer, real, or double-precision scalar.
The largest possible rectangle,

A ratio greater than 1 sets the rectangle to be taller than it is wide,
and a ratio of less than 1 sets the rectangle to be wider than it is tall.
A ratio of 1 yields a rectangle with equal width and height.
Setting the aspect ratio to 0 allows the rectangle to expand to the
size of the full window.

O-Matrix will generate a square plot no matter what the
shape of the plotting window.
