# Lattice structure
|
|
|
|
D-dimensional lattice points are labeled by two ordered integer
|
|
numbers: the point-in-block index ($$b$$ in the figure below) and the
|
|
block index ($$r$$ in the figure below). This is called **natural
|
|
indexing**, in contrast with the **lexicographic indexing** where points on
|
|
the lattice are represented by a D-dimensional `CartesianIndex`.
|
|
The routines [`up`](@ref) and
|
|
[`dw`](@ref) allow you to displace to the neighboring points of the
|
|
lattice.
|
|
|
|
|
|
Directions are numbered fro 1 to D, and then Euclidean time is always
|
|
assumed to be the last coordinate. Planes are also numbered from 1 to
|
|
$$N(N-1)/2$$. The structure [`SpaceParm`](@ref)
|
|
contains the information of the
|
|
lattice structure and has to be passed as argument to most routines.
