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

1 2 |

`gtinput` |
Gabor transform, output of |

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

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

`nvoice` |
number of different frequencies. |

`freqstep` |
sampling rate for the frequency axis. |

`scale` |
scale of the window. |

`Qinv` |
inverse of the matrix |

`epsilon` |
coefficient of the |

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

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

`check` |
if set to TRUE, computes |

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

`sol` |
reconstruction from a ridge. |

`A` |
<gaborlets,dualgaborlets> matrix. |

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

`dualwave` |
array containing the dual gaborlets. |

`gaborets` |
array of gaborlets located on the ridge samples. |

`solskel` |
Gabor transform of sol, restricted to the ridge. |

`inputskel` |
Gabor transform of signal, restricted to the ridge. |
