Change Log for LTPDA Toolbox V0.2
---------------------------------

M Hewitson 31-05-07

Version 0.2 of the toolbox most notably uses no mex files (all replaced by MATLAB code) and
includes significant improvements to the underlying AO infrastructure. In addition to the
numerous small improvements, the following list of additions is in V0.2.

New Classes
-----------

+ xydata for storing arbitrary X-Y data sets
+ mfir for FIR filtering
+ provenance for storing machine details (IP, OS, hostname, etc)

AO Class Functionality
----------------------

New constructor methods:
	'waveform' constructor
	create AO from spectral window
	create AO from valid MATLAB function which returns vector/matrix of values
	create AO from any valid MATLAB function of 't'

New math functions: 
	sin, cos, tan, asin, acos, atan
	log ln exp
	mean median var std
	decimate
	sum
	hist - make histograms
	
New operators:
	* / for matrix multiplication and division. Works only with cdata AOs
	.' ' transpose and complex transpose
	
New matrix operations for cdata AOs:
	eig - compute eigenvalues
	det - compute determinant
	inv - compute inverse
	svd - singular value decomposition
	diag - diagonalise matrix
	norm - compute norm of matrix
	inner/outer products
	
New utility functions:
	find   - find values in AO
	select - select sub-set of samples in AO
	index  - index into Matrix of AOs

New plot type: stairs

New features
------------

+ More comprehensive examples directory
+ New analyses folder for 3rd party analyses
+ New signal-processing algorithms:
	+ ltpda_ltfe - compute transfer function estimates on a log frequency axis
	+ ltpda_linedetect - automatically find spectral lines 
	+ All cross-spectral functions are multivariate now and return full matrix of
	  possible measurements.
