support

Returns support of compactly supported wavelets.

DESCRIPTION

USAGE

support(filter.number=10, family="DaubLeAsymm", m=0, n=0)

REQUIRED ARGUMENTS

filter.number

The member index of a wavelet within the family. For Daubechies' compactly supported wavelet this is the number of vanishing moments which is related to the smoothness. See filter.select for more information on the wavelets.

family

The family of wavelets. See filter.select for more information on the wavelets.

OPTIONAL ARGUMENTS

m

Optional scale value (in usual wavelet terminology this is j)

n

Optional translation value (in usual wavelet terminology, this is k)

VALUE

lh Left hand support of the wavelet with scale m and translation n. These values change as m and n (although when m=0 the function confusingly returns the next coarser wavelet where you might expect it to return the mother. The mother is indexed by m=-1)

rh As lh but returns the rh end.

psi.lh

left hand end of the support interval for the mother wavelet (remains unchanged no matter what m or n are)

psi.rh

right hand end of the support interval for the mother wavelet (remains unchanged no matter what m or n are)

phi.lh

left hand end of the support interval for the father wavelet (remains unchanged no matter what m or n are)

phi.rh

right hand end of the support interval for the father wavelet (remains unchanged no matter what m or n are)

#
# What is the support of a Haar wavelet?
#
support(filter.number=1, family="DaubExPhase", m=0, n=0)
#$lh
#[1] 0
#
#$rh
#[1] 2
#
#$psi.lh
#[1] 0
#
#$psi.rh
#[1] 1
#
#$phi.lh
#[1] 0
#
#$phi.rh
#[1] 1
#
# So the mother and father wavelet have support [0,1]
