14.4.6 Finding the barycenter of a set of points in space: barycenter
See Section 13.6.10 for barycenters of objects in the
plane.
The barycenter command returns and draws the barycenter of a set of
weighted points.
barycenter takes an unspecified number of arguments: L1,L2,…,Ln, a sequence of lists of length two, where
each list consists of a point and a weight. This information can
also be given as a matrix with two columns (the first column the
points and the second column the weights) or a matrix with two rows
and more than two columns.
barycenter(L1,L2,…,Ln) draws and
returns the barycenter of the weighted points.
If the sum of the weights is zero, then this
command returns an error.
