`addelman_const`

implements the Addelman and Kempthorne construction of orthogonal arrays of strength two.

1 | ```
addelman_const(dimension, levels, choice="U")
``` |

`dimension` |
The number of columns of the orthogonal array. |

`levels` |
The number of levels of the orthogonal array. Either a prime number or a prime power number. |

`choice` |
A character from the list ("U","V","W","X") specifying which orthogonal array to construct (see "Details"). |

The method of Addelman and Kempthorne allows to construct up to four orthogonal arrays. `choice`

specify which orthogonal array is to be constructed. Note that the four orthognal arrays depends on each others through linear equations.

A matrix corresponding to the orthogonal array constructed.
