.BG
.FN ridrec
.TL
Reconstruction from a Ridge
.DN
Reconstructs signal from sample of a ridge,
in the wavelet case.
.CS
ridrec(cwtinput, node, phinode, noct, nvoice, Qinv, epsilon, np, w0=2 * pi, check=F, real=F)
.RA
.AG cwtinput
wavelet transform, output of "cwt".
.AG node
time coordinates of the ridge samples.
.AG phinode
scale coordinates of the ridge samples.
.AG noct
number of octaves (powers of 2).
.AG nvoice
number of different scales per octave.
.AG Qinv
inverse of the matrix $Q$ of the quadratic form.
.AG epsilon
coefficient of the Q_2 term in reconstruction kernel
.AG np
number of samples of the reconstructed signal.
.OA
.AG w0
central frequency of Morlet wavelet.
.AG check
if set to T, computes "cwt" of reconstructed signal.
.AG real
if set to T, uses only constraints on the real part
of the transform.
.RT
Returns a list containing the reconstructed signal and the chained ridges.
