Description Usage Arguments Details Value See Also Examples

Create an object of class `"VecLat"`

representing a 3D
face-centered rectangular
vector lattice.

1 | ```
FCRectLat3(d=1,dx=sqrt(2)*d,dz=d)
``` |

`d` |
the distance between two neighbour diagonal locations on the horizontal plane. Default: 1. |

`dx` |
the distance between two neighbour locations along the x-axis on the horizontal plane. Default: |

`dz` |
the vertical spacing between two neigbour horizontal planes. Default: d. |

Note that the default arguments do not define a face-centered cubic
lattice. A face-centered rectangular lattice is considered as a series
of horizontal quincunx 2D lattices. The arguments d and dx define the
spacings of the horizontal quincunx. The default values of d and dx
yields unit horizontal quincunx lattices. A quincunx lying in a given
horizontal plane is shifted halfway in a single direction into the next
horizontal plane. The argument dz defines the distance separating two
consecutive horizontal planes. The unit face-centered cubic lattice is
obtained with *d=sqrt(2)/2*, *dx=1* and *dz=0.5*.
