Syntax

[Xc,Yc]=polycentroid(X,Y);

Description

This function computes the centroid of a polygon.

Assumes row vectors or matrices whereby each row describes a polygon with points appearing in the order defining the polygon

Examples

V=[0 0 0; 1 0 0; 1 1 0; 0 1 0];

[Xc,Yc]=polycentroid(V(:,1)',V(:,2)')

Xc =

    0.5000


Yc =

    0.5000

F=[1 2 3 4]; %Face

cFigure; hold on;
gpatch(F,V,'w','k',0.5);
plotV(V,'k.','MarkerSize',25)
plot(Xc,Yc,'r.','MarkerSize',50)
