## Miscellaneous Functions for Dual-Tree Wavelet Software

### Description

Miscellaneous functions for dual-tree wavelet software.

### Usage

    cshift(x, m)
    cshift2D(x, m)
    pm(a, b)

### Arguments

`x` | N-point vector
`m` | amount of shift
`a,b` | input parameters

### Value

`y` | vector `x` will be shifed by `m` samples to the left or matrix `x` will be shifed by `m` samples down.
`u` | (a + b) / sqrt(2)
`v` | (a - b) / sqrt(2)
