R: Sampling wavelet Ridge

wRidgeSampling {Rwave} | R Documentation

## Sampling wavelet Ridge

### Description

Given a ridge phi (for the wavelet transform), returns a (appropriately) subsampled version with a given subsampling rate.

### Usage

    wRidgeSampling(phi, compr, nvoice)

### Arguments

`phi` | ridge (1D array).
`compr` | subsampling rate for the ridge.
`nvoice` | number of voices per octave.

### Details

To account for the variable sizes of wavelets, the sampling rate of a wavelet ridge is not uniform, and is proportional to the scale.

### Value

Returns a list containing the discrete values of the ridge.

`node` | time coordinates of the ridge samples.
`phinode` | scale coordinates of the ridge samples.
`nbnode` | number of nodes of the ridge samples.
