Wavelet manager
Use wavemngr
to add, delete, restore, or read
wavelets.
wavemngr('add',
adds a wavelet family to the toolbox. These parameters define the wavelet family:FN
,FSN
,WT
,NUMS
,FILE
)
FN
— Family name
FSN
— Family short name
WT
— Wavelet family type
NUMS
— Wavelet parameters
FILE
— Wavelet definition file
Note
When you use wavemngr
to add a wavelet family,
three wavelet extension files are created in the current folder: the two
ASCII files wavelets.asc
and
wavelets.prv
, and the MAT-file
wavelets.inf
. If you add a new wavelet family, it
is available in this folder only.
wavemngr('restore')
restores the previous
wavelets.asc
ASCII file
wavemngr('restore',IN2)
restores the initial
wavelets.asc
ASCII file. Here IN2
is a
dummy argument.
returns all
wavelet family names in a character array.out
= wavemngr('read')
returns
all wavelet names in a character array. Here out
= wavemngr('read',IN2)IN2
is a dummy
argument.
reads the
out
= wavemngr('read_asc')wavelets.asc
ASCII file and returns all wavelet
information.
wavemngr
allows you to add a wavelet. You must verify
that it is truly a wavelet. No check is performed to confirm the addition is a
wavelet or to confirm the type of the new wavelet. You can use dwtfilterbank
to verify if a wavelet is orthogonal or
biorthogonal.
