One axis of the three-dimensional array is translated by an integer amount. This is useful when applying convolution operators in the Fourier domain.

`A` |
is a three-dimensional array. |

`s` |
is the integer number of translation steps. |

`type` |
is a character string using anatomical coordinates assuming a transverse acquisition scheme (“LR” = left-right = x-axis, “AP” = anterior-posterior = y-axis, “SI” = superior-inferior = z-axis). |

`fill` |
is the quantity used to fill gaps induced by the translations (circular boundary conditions are NOT used). |

A three-dimensional array is returned, the same dimension as the original array, with one dimension translated.
