How can I make my function plot lines to make a rectangle?

Hi, I can't figure out how to make my function plot lines.

Here is my code.

clear all, format compact, format shortg; close all; fclose all; clc;

% Rectangle 1

rect1.pos= [30,20]; % x and y coordinates of the lower left corner

rect1.width = 500;

rect1.height= 400;

rect1.color = 'b';

figure(1)

draw_rect_Eduardo_Gallegos_call(rect1)

axis equal;

% Rectangle 2

rect2.pos= [350,300]; % x and y coordinates of the lower left corner

rect2.width = 220;

rect2.height= 250;

rect2.color = 'r';

draw_rect_Eduardo_Gallegos_call(rect2)

% Rectangle 3

rect3.pos= [300,250]; % x and y coordinates of the lower left corner

rect3.width = 150;

rect3.height= 400;

rect3.color = 'c';

hold on;

draw_rect_Eduardo_Gallegos_call(rect3)

Here is the function code

function [] = draw_rect_Eduardo_Gallegos_call(rect)

plot(rect.height,rect.width,'o' )

end

Hi,

Your function just plots one point. You need to plot all the points of your rectangle, and closing it by returning at the first point.

This should work as you want

function [] = draw_rect_Eduardo_Gallegos_call(rect)
    plot([rect.pos(1) rect.pos(1) rect.pos(1)+rect.width rect.pos(1)+rect.width rect.pos(1)], ...
        [rect.pos(2) rect.pos(2)+rect.height rect.pos(2)+rect.height rect.pos(2) rect.pos(2)], ...
        'Color',rect.color)
end
