Extend the data as the exponential of base N by increasing row number.

1 | ```
extendNBase(x, nLevel=1, base=2, ...)
``` |

`x` |
data matrix |

`nLevel` |
the level of DWT decomposition. Basically, it is equivalent to changing the 'base' as base\^nLevel |

`base` |
the base, 2 by default |

`...` |
other parameters of used by |

The method 'open' is padding the the matrix with the last row.

Return a extended matrix
