ScalingFunction: Compute scaling functions on internally predefined grid

In wavethresh: Wavelets Statistics and Transforms

Compute scaling functions on internally predefined grid

Description

This is a subsidiary routine not intended to be called by a user: use draw instead. Generates scaling functions by inserting a Kronecker delta function into the bottom of the inverse DWT and repeating the inverting steps.

Usage

ScalingFunction(filter.number = 10, family = "DaubLeAsymm", resolution = 4096,
    itlevels = 50)

Arguments

filter.number	The filter number of the associated wavelet. See filter.select
family	The family of the associated wavelet. See filter.select
resolution	The nominal resolution, the actual grid size might be larger than this
itlevels	The number of complete filtering operations to generate the answer

Value

A list containing the x and y values of the required scaling function.
