VecLat-class: Class "VecLat"

Description Objects from the Class Slots Methods References See Also

Description

Objects of class "VecLat" represent vector lattices.

Objects from the Class

Objects can be created by calls of the form new("VecLat", ...) or using generators such as VecLat, RectLat2, HexLat2.

Slots

dimspace:

Object of class "numeric". Dimension of the space where the lattice lies.

dimsupp:

Object of class "numeric". Dimension of the support of the lattice, defined as the smallest vector subspace containing the lattice.

gmat:

Object of class "matrix". Generating matrix of the lattice.

gmat0:

Object of class "matrix". Unit version of the generating matrix.

det:

Object of class "numeric". Determinant of the lattice.

Methods

ltransf

signature(x = "VecLat", m = "matrix"): ltransf for a VecLat object.

print

signature(x = "VecLat"): print a VecLat object.

scaling

signature(x = "VecLat", s = "numeric"): scaling for a VecLat object.
