TSA (Time Series Analysis) Toolbox 2.40
=======================================

The TSA toolbox is useful for analysing (univariate, stationary) 
Time Series. In comparison to other signal processing tools, the
methods used here, are based on maximum entropy methods.
It can be used for
- Stochastic Signal processing 
- Autoregressive Model Identification 
- matched (inverse) filter design
- Histogram analysis <NEW>  
- Calcution of the entropy of a time series
- Non-linear analysis (3rd order statistics) 
- Time-varying and Non-stationary Analysis <in preparation>
	Recursive Least squares (RLS) algorithm
	Least Mean Square (LMS) algorithm
- Test for UnitCircle-Polynomials <NEW>
- Test for Hurwitz-Polynomials <NEW>
- multiple signal processing 

Several criteria (AIC, BIC, FPE, MDL, SBC, CAT, PHI) for 
the selection of the order of an autoregressive model are included.
Furthermore includes the toolbox a fast version if the Yule-Walker method 
for estimating Autoregressive parameters, the Autocovariance Function (ACovF), 
Autocorrelation Function (ACF), Partial ACF (PACF), and some 
other useful staff. Demo programs can be started with "demo" or "demotsa". 

Modifications of V2.40:
From Version 2.32 and higher many functions can be used for multiple 
channels.
