Ellipse explicitly defined

Syntax: ELLIPSE a b xc yc angle
ELLIPSE\POPULATE a b xc yc angle
ELLIPSE\POPULATE\NPTS a b xc yc angle n
ELLIPSE\POPULATE\XYOUT a b xc yc angle xout yout
ELLIPSE\POPULATE\XYOUT\NPTS a b xc yc angle n xout yout

By default, the input parameters are assumed to be scalars representing the major axis radius, a, the minor axis radius, b, the coordinates of the centre, cx and cy, and the angle of the ellipse, angle, in degrees, measured counter-clockwise from the horizontal.

Parameter order

The order in which the qualifiers appear is irrelevant. The order in which the command parameters appear is fixed: a b xc yc angle { npts } { xout yout }
