centroid

Compute the centroid (center of mass) of a set of points.

Usage

PTS = centroid(POINTS)
PTS = centroid(PTX, PTY)

Computes the ND-dimensional centroid of a set of points. POINTS is an array with as many rows as the number of points, and as many columns as the number of dimensions. PTX and PTY are two column vectors containing coordinates of the 2-dimensional points. The result PTS is a row vector with Nd columns.

PTS = centroid(POINTS, MASS)
PTS = centroid(PTX, PTY, MASS)

Computes center of mass of POINTS, weighted by coefficient MASS. POINTS is a Np-by-Nd array, MASS is Np-by-1 array, and PTX and PTY are also both Np-by-1 arrays.

Example

pts = [2 2;6 1;6 5;2 4];
centroid(pts)
ans =
     4     3
