Reconstructs signal from sample of a ridge, in the wavelet case.

1 2 |

`cwtinput` |
wavelet transform, output of |

`node` |
time coordinates of the ridge samples. |

`phinode` |
scale coordinates of the ridge samples. |

`noct` |
number of octaves (powers of 2). |

`nvoice` |
number of different scales per octave. |

`Qinv` |
inverse of the matrix |

`epsilon` |
coefficient of the |

`np` |
number of samples of the reconstructed signal. |

`w0` |
central frequency of Morlet wavelet. |

`check` |
if set to TRUE, computes |

`real` |
if set to TRUE, uses only constraints on the real part of the transform. |

Returns a list containing the reconstructed signal and the chained ridges.

`sol` |
reconstruction from a ridge |

`A` |
<wavelets,dualwavelets> matrix |

`lam` |
coefficients of dual wavelets in reconstructed signal. |

`dualwave` |
array containing the dual wavelets. |

`morvelets` |
array of morlet wavelets located on the ridge samples. |

`solskel` |
wavelet transform of sol, restricted to the ridge |

`inputskel` |
wavelet transform of signal, restricted to the ridge |
