R: Weight a Fourier series sequence by a set of weights

rfftwt {wavethresh} | R Documentation

## Weight a Fourier series sequence by a set of weights

### Description

Weight the real Fourier series `xrfft` of even length by a weight sequence `wt`. The first term of `xrfft` is left alone, and the weights are then applied to pairs of terms in `xrfft`. Note: `wt` is half the length of `xrfft`.

### Usage

    rfftwt(xrfft, wt)

### Arguments

`xrfft` | The Fourier series sequence to weight
`wt` | The weights

### Details
