Reconstruction from Dual Wavelets

Computes the the reconstructed signal from the ridge when the epsilon parameter is set to zero, in the case of real constraints.

zeroskeleton2(cwtinput, Qinv, morvelets, bridge, aridge, N)

`cwtinput`	continuous wavelet transform (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.
