iswt

Inverse Stationary Wavelet Transform

Calling Sequence

x0=iswt(SWA,SWD,wname])
x0=iswt(SWA,SWD,Lo_R,Hi_R)
x0=iswt(SWC,wname])
x0=iswt(SWC,Lo_R,Hi_R)

Parameters

SWA
: approximation coefficient
SWD
: detail coefficient
SWC
: composite coefficient
wname
: wavelet name, haar( "haar"), daubechies ("db1" to "db20"), coiflets ("coif1" to "coif5"), symlets ("sym2" to "sym20"), legendre ("leg1" to "leg9"), bathlets("bath4.0" to "bath4.15" and "bath6.0" to "bath6.15"), dmey ("dmey"), beyklin ("beylkin"), vaidyanathan ("vaidyanathan"), biorthogonal B-spline wavelets ("bior1.1" to "bior6.8"), "rbior1.1" to "rbior6.8"
x0
: reconstruced signal
Lo_R
: lowpass synthesis filter
Hi_R
: highpass synthesis filter

Description

iswt is discrete inverse stationary wavelet transform utility.

Examples

x=rand(1,128);
[SWA,SWD]=swt(x,3,'db2');
x0 = iswt(SWA,SWD,'db2');
