pgrid: Constructor for the pgrid Class

In transport: Computation of Optimal Transport Plans and Wasserstein Distances

Constructor for the pgrid Class

Description

Construct an object of class "pgrid" from a matrix or a higher-dimensional array.

Usage

  pgrid(mass, boundary, gridtriple, generator, structure) 

Arguments

mass	a matrix or higher-dimensional array specifing the masses in each pixel / at each pixel centre.
boundary, gridtriple, generator	arguments specifying the positions of the pixels. At most one of these can be specified.
structure	optional character string specifying the structure of the grid. Currently only "square" and "rectangular" make sense, and are derrived automatically from the dimensions of mass.

Details

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