RELEASE NOTES FOR THE KALMTOOL TOOLBOX, VERSION 2
=================================================

This note contains important information on how the present
toolbox is to be installed, and the conditions under which it may
be used. Please read it carefully before use.

BEFORE YOU START USING THE TOOLBOX
After installation, all toolbox functions will be located in one
directory, and the files associated with the demonstration
programs will be located in a subdirectory under this. The user
should make a path to these directories with the MATLAB function
"path":
   >> path(path,'/xx/.../xx/Kalmtool');
   >> path(path,'/xx/.../xx/Kalmtool/Demo');
If the toolbox is going to be used on a regular basis it is
recommended to include this statement in the file 
"startup.m", which is invoked during the start of MATLAB.

If a C compiler is available, and the MATLAB "mex" command has
been set up, the MEX functions in the demonstration directory
are compiled with:
   >> cd /xx/xx/.../Kalmtool/Demo
   >> demomex

This script invokes the "mex" command for each of the
MEX functions in the demonstration directory.

The manual for the toolbox is available as a pdf-file. The file
is called "kalmman.pdf".

A technical report describing the filters in detail is available
in the postscript file "revddfilt.ps".


CONDITIONS/DISCLAIMER
By using the toolbox the user agrees to all of the following:

o   If one is going to publish any work where this toolbox has
    been used, please include a reference to the article:
    M. Norgaard, N.K. Poulsen, O. Ravn: New Developments in State
    Estimation for Nonlinear Systems, Automatica, (36:11), 
    Nov. 2000, pp. 1627--1638.

o   Magnus Norgaard does not provide any support for this
    product whatsoever.

o   The Kalmtool toolbox is shareware. The "limited version", 
    which is the one available from the internet, does not 
    include the C source code for the mex-files. The "full 
    version" is the same as the "limited version", but it 
    includes the source code. The conditions for use are the
    same for the two versions. The full license can currently be
    obtained for 85USD/95EUR (single-user license) or
    150USD/170EUR (multi-user license). The price does not
    include support. Please contact the author by e-mail for
    registration details.

    The registration requirements are the following:
    >>> For education and research at the Technical University
    of Denmark (DTU): Limited and full versions are free.

    >>> For full-time registered undergraduate and graduate
    students and for university researchers: The limited version
    is free. 

    >>> Others: Everyone else are free to download and evaluate
    the toolbox for a 30 day period but are required to obtain a
    "full license" for use beyond 30 days.

    >>> Exceptions: None. Requests for free access to the source 
    code will not be answered.

o   It is not permitted to utilize any part of the software in
    commercial products without prior written consent of Magnus
    Norgaard.
