COI: Computation of the cone of influence

Description

Wavelet transformation of a time series includes padding with zeros at the edges. This function determines the spectrum borders influenced by edge effects.

This code has been developed by Huidong Tian (archived R package WaveletCo).

Usage

COI(start = start, dt = dt, nc = nc, nr = nr, Period = Period)

Arguments

start
starting value (in time units) at the time axis
dt
time resolution, i.e. sampling resolution on time domain
nc
number of columns/time steps
nr
number of rows/scales
Period
the Fourier periods (in time units)

Value

x, y :
coordinates of the cone of influence x, y
