VecLat-class: Class "VecLat"
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.
