Reconstruction from Dual Wavelet

Computes the reconstructed signal from the ridge in the case of real constraints.

skeleton2(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.

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.
