Computes the Forward WaveD Transform.

1 |

`y` |
Sample of |

`g` |
Sample of |

`L` |
Lowest resolution level; the default is 3. |

`deg` |
The degree of the Meyer wavelet, either 1, 2, or 3 (the default). |

`F` |
Finest resolution level; the default is the data-driven choice j1 (see Value below). |

`thr` |
A vector of length |

`SOFT` |
if SOFT=TRUE, uses the soft thresholding policy as opposed to the hard (SOFT=FALSE, the default). |

Returns a vector of wavelet coefficients of length n (the same length as y),
the last *n/2* entries are wavelet coefficients at resolution level *J-1*, where
*J= log_2(n)*; the *n/4* entries before that are the wavelet coefficients at
resolution level *J-2*, and so on until level L. In addition the *2^L* entries
are scaling coefficients at coarse level *C=L*.
