Makes coordinates for a regualr polygon
Generates an n x 2 matrix containing x and y coordinates between 1 and 0 for the points of a regular polygon.
polygon_coords(n = 5, x = 0, y = 0, radius = 1, angle = 0)
numericof length 1) The number of nodes in the polygon.
numericof length 1) x coordinate of center
numericof length 1) y coordinate of center
numericof length 1) The diameter of the circle.
numericof length 1) Angle to rotate points around the center of the circle.
