skeleton: Reconstruction from Dual Wavelets

In Rwave: Time-Frequency Analysis of 1-D Signals

Reconstruction from Dual Wavelets

Description

Computes the reconstructed signal from the ridge, given the inverse of the matrix Q.

Usage

skeleton(cwtinput, Qinv, morvelets, bridge, aridge, N)

Arguments

cwtinput	continuous wavelet transform (as the output of cwt)
Qinv	inverse of the reconstruction kernel (2D array)
morvelets	array of Morlet wavelets located at the ridge samples
bridge	time coordinates of the ridge samples
aridge	scale coordinates of the ridge samples
N	size of reconstructed signal

Value

Returns a list of the elements of the reconstruction of a signal from sample points of a ridge

sol	reconstruction from a ridge
A	matrix of the inner products
lam	coefficients of dual wavelets in reconstructed signal. They are the Lagrange multipliers lambda's of the text.
dualwave	array containing the dual wavelets.
