Change Log for LTPDA Toolbox V0.3
---------------------------------

M Hewitson 30-06-07


Version 0.3 of the toolbox sees mainly work on the infrastructure of AOs. Some additional signal processing
commands have been introduces, and those that can work (sensibly) in a multivariate way, now do. 

All AO class functions and signal processing functions now respond to a call like foo('Params') or, in the case of
AO class methods, foo(ao, 'Params') to return default parameter lists.

One noticeable change is that there is the beginnings of a fully integrated help document for the toolbox. You
can now browse the toolbox help in MATLAB's help browser (>> doc ltpda).

The direct SIMULINK GUI (gltpda) is now in the CVS and an alpha version is included in this release. To start the
GUI, type startltpgui at the MATLAB prompt.

The parser SIMULINK GUI (sltpda) now supports nested loop blocks.

This release includes a first version of a graphical AO browser. Start the GUI by doing explore_ao, or
explore_ao(a) where 'a' is an AO.

AO Class
--------

+ Saving and loading AOs from .MAT files works now.

New methods:

	polyfit   - polynomial fit to data in AO. Returns fit as a new AO.
	interp    - interpolation function for AOs. 
	join      - join AOs together.
  	
Signal Processing
-----------------

All frequency-domain signal processing functions are now multivariate, where appropriate. 

New functions:
	
	ltpda_xcorr   - multivariate cross-correlation function.
