Reconstruction from Dual Wavelets

Computes the the reconstructed signal from the ridge when the epsilon parameter is set to zero

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

`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.

The details of this reconstruction are the same as for the function skeleton. They can be found in the text

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.
