The routine returns the length of the minor axis of the given ellipse e.

The line segment through the center and perpendicular to the major axis is called the minor axis.

The command with(geometry,MinorAxis) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{geometry}\right)\:$

$\mathrm{ellipse}\left(\mathrm{e1}\,2x^2+y^2-4x+4y=0\,\left[x\,y\right]\right)\:$

$\mathrm{MinorAxis}\left(\mathrm{e1}\right)$

$2\sqrt{3}$
