R: Compute scaling functions on internally predefined grid

ScalingFunction {wavethresh}

R 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.
