## Extend the row number of a matrix as the exponential of base N

### Description

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

### Usage

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

### Arguments

`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 `extendLength`
