wpp: Constructor for the wpp Class

In transport: Computation of Optimal Transport Plans and Wasserstein Distances

Constructor for the wpp Class

Description

Construct an object of class "wpp" from a matrix of points and a vector of masses.

Usage

  wpp(coordinates, mass)

Arguments

coordinates	a matrix specifying the coordinates of the points. Each row corresponds to a point.
mass	a vector of non-negative values specifying the masses at these points.

Details

For more detailed explanations of the arguments and other components of the returned object of class "wpp", see wpp-object.

It is legitimate to assign mass 0 to individual points in the arguments. However, when constructing the wpp-object such points are deleted. The coordinates of the deleted points can still be accessed via the attribute zeropoints.
