Multilevel 3-D wavelet decomposition

`WDEC = wavedec3(X,N,`

* 'wname'*)

WDEC = wavedec3(X,N,

`'wname'`

`'ExtM'`

WDEC = wavedec3(X,N,{LoD,HiD,LoR,HiR})

`wavedec3`

is a three-dimensional
wavelet analysis function.

`WDEC = wavedec3(X,N,`

returns
the wavelet decomposition of the 3-D array * 'wname'*)

`X`

at
level `N`

, using the wavelet named in character vector `'wname'`

`'sym'`

. See `dwtmode`

. `N`

must
be a positive integer.`WDEC = wavedec3(X,N,`

uses
the specified DWT extension mode . * 'wname'*,'mode',

`'ExtM'`

`WDEC = wavedec3(X,N,{LoD,HiD,LoR,HiR})`

uses
the decomposition and reconstruction filters you specify in a cell
array.

`WDEC`

is the output decomposition structure,
with the following fields:

`sizeINI` | Size of the three-dimensional array |

`level` | Level of the decomposition |

`mode` | Name of the wavelet transform extension mode |

`filters` | Structure with 4 fields, |

`dec` |
For
example, if At
each level, the wavelet coefficients in The
character vectors give the order in which the separable filtering
operations are applied from left to right. For example, |

`sizes` | Successive sizes of the decomposition components |
