MATLAB exercise program (simple polygon Construction)

A simple polygon is a polygon with different edges.

Calculate the center position of all vertices.

Then obtain the polar angle between each vertex and the center.

Then sort the polar angles.

Connect the sorted points.

The result is as follows:

The Matlab code is as follows:

Clear all; close all; clc; n = 30; P = rand (n, 2); CEN = mean (p); Ang = atan2 (P (:, 1) -CEN (1), P (:, 2)-CEN (2); % P = [p, Ang]; P = sortrows (p, 3); % Hold on by polar angle; % connect each point plot (P (:, 1), P (:, 2); P = circshift (P, 1 ); plot (P (:, 1), P (:, 2 ));
