In shimlab/HMTree: Hidden Markov tree prior for analysis of multiple functional data

Description

Reflecting the signal in wavelet applications allows the signal to be periodic and usually lessens boundary bias. If the original signal has a length which is a power of 2, this function adds a reflection of the original signal to itself. Otherwise this function extends the original signal to have length of a power of 2 by reflecting an appropriate number of observation points, and then reflecting the entire modified signal.

Usage

reflectSignal(x)

Arguments

x	an m by n matrix of signals

Value

an n-vector containing the indices of the smoothed output corresponding to the original signal x. Also substitutes the original signal with the reflected one to be used as input.
