wfilters - wavelet filter set

Calling Sequence

[Lo_D,Hi_D,Lo_R,Hi_R]=wfilters(wname)

[Lo_D,Hi_D]=wfilters(wname,'d')

[Lo_R,Hi_R]=wfilters(wname,'r')

[Lo_D,Lo_R]=wfilters(wname,'l')

[Hi_D,Hi_R]=wfilters(wname,'h')

Parameters

• wname : wavelet name
• Lo_D : lowpass analysis filter
• Hi_D : highpass analysis filter
• Lo_R : lowpass synthesis filter
• Hi_R : highpass synthesis filter

Description

wfilters is an utility function for obtaining analysis and synthesis filter set.
