generate 2-D plot object for an ellipse
ellipse(c, a, b, opts)
center of the ellipse
horizontal radius of the ellipse
vertical radius of the ellipse
(optional) equations of the form option=value
Any applicable 2-D plot option in plot/options can also be given.
filled : truefalse
Specifies whether to fill the inside of the ellipse. The default is false.
rotate = real
Specifies that ellipse should be be rotated by the specified angle (in radians). The default is 0.
super = positive real, list of two positive reals, or the value true
The super option given alone is equivalent to super=m (with m=4) which is equivalent to super=[m,m]. More generally ellipse([x0, y0], a, b, super=[m1,m2]) draws the superellipse (or generalized superellipse when m1≠m2)
The ellipse command creates a two-dimensional plot data object, which when displayed is an ellipse centered at c with radial distances a and b, that is, ellipse([x0, y0], a, b) draws the ellipse
The super option may be used to draw a superellipse or generalized superellipse.
The plot data object produced by the ellipse command can be used in a PLOT data structure, or displayed using the plots[display] command.
Remaining arguments are interpreted as options, which are specified as equations of the form option = value. For more information, see plottools and plot/options.
Draw an ellipse described by the following equation,
a ≔ 2:b ≔ 3:x0 ≔ 0:y0 ≔ 0:
elli ≔ ellipse⁡x0,y0,a,b,filled=true,color=blue:
which is equivalent (apart from the filled option) to:
eq ≔ x−x02a2+y−y02b2=1:
Ellipse in arbitrary forms can be generated with object transformations such as rotate in the plots package.
ms ≔ 13,12,23,1,32,2,3,5
The super option was introduced in Maple 2019.

The plottools[ellipse] command was updated in Maple 2023.
The rotate option was introduced in Maple 2023.
