The issue lies in how "voronoi" is being called - its syntax expects two equal-length vectors of x and y coordinates. In the shared code, multiple range expressions are passed, which leads to the following error:
voronoi((0.7:2),(0.8:1),(2:2.1),(1.7:0.8));
To segment a triangle using "voronoi", you need to provide a set of seed points located within or around the triangle. For more details on the correct syntax, refer to the official documentation:
Here is a minimal example for reference:
close all; clear; clc
figure()
x = [0.5, 2, 3.7];
y = [0.6, 3.1, 1.2];
fill([x x(1)], [y y(1)], 'w');
axis([0 4 0 3]); axis equal; hold on;
voronoi([1.5, 2.5, 2], [1.2, 2.2, 1.8]);
