Create a 2D Cartesian circle or arc.


circle = makeCartCircle(radius, num_points)
circle = makeCartCircle(radius, num_points, center_pos)
circle = makeCartCircle(radius, num_points, center_pos, arc_angle)
circle = makeCartCircle(radius, num_points, center_pos, arc_angle, plot_circle)


makeCartCircle creates a 2 x num_points array of the Cartesian coordinates of points evenly distributed over a circle or arc (if arc_angle is given). The plot that is displayed after calling makeCartCircle(10, 100, [0,0], (215/180)*pi, true); is given below.


radius circle radius [m]
num_points number of points on the circle

Optional Inputs

center_pos [x, y] position of the circle center [m] (default = [0, 0])
arc_angle arc angle for incomplete circle [radians] (default = 2*pi)
plot_circle Boolean controlling whether the Cartesian points are plotted using plot (default = false)


circle 2 x num_points array of Cartesian points
