"""Spectral Analysis Tools using the Multitaper Methodi
Implements multitaper spectral analysis using discrete prolate spheroidal
sequences (Slepians) and sine tapers. It includes an adaptive weighted
multitaper spectral estimate, a coherence estimate, Thomson's Harmonic
F-test, and complex demodulation. The Slepians sequences are generated
efficiently using a tridiagonal matrix solution, and jackknifed confidence
intervals are available for most estimates. This package is an
implementation of the method described in D.J. Thomson (1982) "Spectrum
estimation and harmonic analysis" <doi:10.1109/PROC.1982.12433>."""
