av.basis

Perform basis averaging for wst class object

Description

Note: that this function is not for direct user use. This function is a helper routine for the AvBasis.wst function which is the one that should be used by users.

This function works by recursion, essentially it merges the current levels C coefficients from one packet shift with its associated D coefficients, does the same for the other packet shift and then averages the two reconstructions to provide the C coefficients for the next level up.

Usage

av.basis(wst, level, ix1, ix2, filter)

Arguments

`wst`	The `wst.object` that you wish to basis average
`level`	The resolution level the function is currently operating at
`ix1`	Which "left" packet in the level you are accessing
`ix2`	Which "right" packet
`filter`	The wavelet filter details, see `filter.select`

Details

Description says all, see help page for AvBasis.wst.

Value

Returns the average basis reconstruction of a wst.object.
