ExtendToroidalUmatrix | R Documentation |

Extends Umatrix by toroidal continuation of the given Umatrix defined by
`ExtendBorders`

in all four directions.

```
ExtendToroidalUmatrix(Umatrix, Bestmatches, ExtendBorders)
```

`Umatrix` |
[1:Lines,1:Columns] Matrix of Umatrix Heights |

`Bestmatches` |
[1:n, 1:2] Matrix with positions of Bestmatches for n
datapoints, first columns is the position in |

`ExtendBorders` |
number of lines and columns the umatrix should be extended with |

Function assumes that U-matrix is not planaer (has no borders), i.e. is toroidal, and not tiled. Bestmatches are moved to new positions accordingly. Example is shown in conference talk of [Thrun et al., 2020].

`Umatrix` |
[1:Lines+2*ExtendBorders,1:Columns+2*ExtendBorders] Matrix of U-Heights |

`Bestmatches` |
Array with positions of Bestmatches |

Currently can be only used if untiled U-Matrix (the default) is presented, but 4-tiled U-matrix does not work.
