ScalingFunction: Compute scaling functions on internally predefined grid

ScalingFunctionR Documentation

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

Details

Description says all

Value

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