scaling_filter: wavelet scaling filter coefficients

Description

Computes the filter coefficients of the Haar or Daubechies wavelet family with a specific order

Usage

scaling_filter(family, parameter)

Arguments

family

Wavelet family, 'Haar' or 'Daubechies'

parameter

Order of the Daubechies wavelet (equal to twice the number of vanishing moments). The value of parameter can be 2,4,8,10,12,14 and 16.

Value

h

Vector of scaling filter coefficients.

M

Number of vanishing moments.

alpha

Fourier decay exponent.
