clear all
close all
clc
a = input('Dim 1: '); % Width for ex: Dim 1: 5(cm)
b = input('Dim 2: '); % Length for ex: Dim 2: 10(cm)
width = a; 
length = b; 
x_center = 0; % x of the center of the rectangle
y_center = 0; % y of the center of the rectangle
xl = x_center - width/2;
yb = y_center - length/2;
rectangle('Position',[xl, yb, width, length]) % I have to eliminate this line and reformulate it without using "rectangle" command
grid on
xlim([-100, 100]);
ylim([-100, 100]);
xL = xlim;
yL = ylim;
line([0 0], yL)  
line(xL, [0 0])

Can anyone tell me what code stands for the rectangular command? I need to know so that I can use it to eliminate the actual command in the code above. I really need help with this.

Thank you!
