This function returns a character string according to a particular format for naming PhiJ objects.

1 |

`J` |
A negative integer representing the order of the PhiJ object. |

`filter.number` |
The index number of the wavelet used to build the PhiJ object. |

`family` |
The wavelet family used to build the PhiJ object. |

Some of the objects computed by PhiJ take a long time to compute. Hence it is a good idea to store them and reuse them. This function generates a name according to a particular naming scheme that permits a search algorithm to easily find the matrices.

Each object has three defining characteristics: its order, filter.number and family. Each of these three characteristics are concatenated together to form a name.

This function performs exactly the same role as rmname except for objects produced by PhiJ.

A character string containing the name of an object according to a particular naming scheme.
