spinw.rl method

generates reciprocal lattice vectors

Syntax

rlVec = rl(obj, {norm})

Description

rlVec = rl(obj, {norm}) returns the lattice vectors of the reciprocal lattice in a $[3\times 3]$ matrix, with the $a^*$ , $b^*$ and $c^*$ vectors stored in rows.

Examples

To convert from reciprocal lattice unit to Å $^{-1}$ ( $xyz$ Cartesian coordinate system) use: (Q_rlu is a row vector with 3 elements):

Q_xyz =  Q_rlu * rlVect

Input Arguments

obj: spinw object.
norm: If true, the basis vectors are normalized to 1. Default values is false, optional.

Output Arguments

rlVec: Stores the three basis vectors in the rows of matrix with dimensions of $[3\times 3]$ .
