rfftwt

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
