Compute the coordinates of points on an ellipse

Description

Compute the coordinates of points on an ellipse

Usage

ellipse(major, minor, alpha = 0, x = 0, y = 0, n = 100)

Arguments

major, minor	length of the major and minor axis
alpha	angle, in trigonometric convention (from the horizontal, positive counter-clockwise, in radians).
x, y	coordinates of the center of the ellipse (around which the rotation is computed if alpha is not 0).
n	number of points to compute on the ellipse.

Examples

plot(ellipse(10, 5), asp=1)
plot(ellipse(10, 5, alpha=pi/4), asp=1)
plot(ellipse(10, 5, alpha=pi/4, x=3, y=4, n=200), asp=1)
