(spinw-rl)=

# spinw.rl method

## 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):
 
```matlab
Q_xyz =  Q_rlu * rlVect
```
  
## Input Arguments
  
`obj`
: [spinw](#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
  $[3\times 3]$.
