Directories and filenames
The functions in the toolbox are divided across the following directories:
- fwt: fast wavelet transforms and related functions.
- packet: one-dimensional wavelet packets.
- packet2: two-dimensional wavelet packets.
- wdemo: demonstrations.
Use help fwt (or helpwin fwt) etc. to view a list of functions
in the corresponding directory. In this document we describe only the
major programs in each category, there are many other functions that are
either variations or subroutines of those described here.
The following abbreviations are used in the names of functions:
| fwt |
fast wavelet transform |
| i |
inverse |
| msa or ms |
multi-scale analysis |
| ns |
non-standard |
| tns |
tensor product |
| wav |
wavelet |
| wp |
wavelet packet |
| wpa |
wavelet packet analysis |
| wps |
wavelet packet synthesis |
Numbers 1 and 2 refer to the number of dimensions.
