Calculation of centroids of compound figures

This simple application allows you to calculate the centroids of the polygonal composite figures you want. Consider the number of figures entered and create them using the "polyshape" function using the Cartesian coordinates entered for each figure. The centroid of the figure is calculated using the "centroid" function that is typical of MATLAB.

To exemplify its use I leave the following example:

Suppose I want to calculate the centroid of a figure composed of a rectangle 20 in height and 30 in width, and on the left side of that rectangle is a semicircle of radius of 10, and whose diameter coincides with the height of the rectangle.

The data entry would be as follows:

>> centroids
Number of polygons =:
2
This poligo is a circ arc? 1 = Yes or 2 = No: % press 1 if the polygon is an arc of circumference, or 2 if it is not.
2
Vert number = % number of coordinates and entering them for the rectangle
4
Vx1 = 0
Vy1 = 0
Vx2 = 0
Vy2 = 20
Vx3 = 30
Vy3 = 20
Vx4 = 30
Vy4 = 0

This poligo is a circ arc? 1 = Yes or 2 = No: % press 1 if the polygon is an arc of circumference, or 2 if it is not.
1
% Data entry for the semi circumference.

radius =
10
Ori_X =
0
Ori_Y =
10
Ang_ini =
90
Ang_fin =
270

xc = 11.08
yc = 10

It is my first contribution to the page. I hope they are not very hard on me. Thanks for your attention.
