Removal of Boundary Wavelet Coefficients

Description

Removes the first n wavelet coefficients.

Usage

brick_wall(x, wave_filter, method)

Arguments

x

A field<vec> that contains the nlevel decomposition using either modwt or dwt.
wave_filter

A field<vec> containing filter information. Only "haar" is implemented.
method

A string to describe the mode. Choose between "modwt" and "dwt"

Details

The vectors are truncated by removing the first n wavelet coefficients. These vectors are then stored into the field that is returned. Note: As a result, there are no NA's introduced and hence the na.omit is not needed.

Value

A field<vec> with boundary modwt or dwt taken care of.
