%   parcor	(*) partial autocorrelation function
%   biacovf	biautocovariance function (3rd order cumulant)
%   bispec	Bi-spectrum 
%   durlev      (*) solves Yule-Walker equation - converts ACOVF into AR parameters
%   lattice     (*) calcultes AR parameters with lattice method
%   lpc		(*) calculates the prediction coefficients form a given time series
%   invest0	(*) a prior investigation (used by invest1)
%   invest1	(*) investigates signal (useful for 1st evaluation of the data)

%
%   	
%  Conversions between Autocorrelation (AC), Autoregressive parameters (AR), 
%             	prediction polynom (POLY) and Reflection coefficient (RC)  
%   ac2poly 	(*) transforms autocorrelation into prediction polynom
%   ac2rc   	(*) transforms autocorrelation into reflexion coefficients
%   ar2rc	(*) transforms autoregressive parameters into reflection coefficients  
%   rc2ar	(*) transforms reflection coefficients into autoregressive parameters

%
% Test suites
%   tsademo		demonstrates INVEST1 on EEG data
%   invfdemo		demonstration of matched, inverse filtering
%   bisdemo		demonstrates bispectral estimation
%
% (*) indicates univariate analysis of multiple data series (each in a row) can be processed.
% (-) indicates that these functions will be removed in future
