In wavethresh: Wavelets Statistics and Transforms

Evaluate the Donoho and Johnstone Doppler signal.

Description

This function evaluates and returns the Doppler signal from Donoho and Johnstone, (1994).

Usage

doppler(t)

Arguments

t	The domain of the Doppler function (where you wish to evaluate this Doppler function

Details
