File Information
Description

This Simulink library is a collection of
blocks that perform Parameter Identification
through the most rewarded frequency and time
domain linear regression methods. It works
in Matlab 5.3.1 as well as in later versions.

Main examples are:

-) Recursive Least Squares (RLS).
-) Simple Windowed Regression (LLS).
-) Local Weighted Regression (LWR).
-) Fourier Transform Regression (FTR).

Two example on Linear and Nonlinear Aircraft
Parameter Identification are included in the library.

IMPORTANT, all of these blocks REQUIRE SMXL
(the Simulink Matrix Library) freely available in the File exchange section of the MATLAB Central website.

Giampy, October 2001

MATLAB release MATLAB 5.3.1 (R11.1)
Other requirements SMXL (Simulink Matrix Library)

Thanks a lot, you are a life saver

I was just going to program it myself and found a reference in sci.eng.control. Have to check how it works, but this should be really good!

PIL is a more the famous (or less than shoul)python image library :)

Hellol,
I wish the author can complement the files:
Main examples are:
 
-) Recursive Least Squares (RLS).
-) Simple Windowed Regression (LLS).
-) Local Weighted Regression (LWR).
-) Fourier Transform Regression (FTR).
 
 
Two example on Linear and Nonlinear Aircraft

Updated signature and info.xml file.

29 Oct 2003

Changed name, should have done that long ago.

12 May 2005

Renamed everything lowercase

12 May 2005

Removed extra dir info from zip file

07 Feb 2007

Changed info.xml file to avoid annoying messages within the last matlab versions.

20 Dec 2008

Streamlined the nonlinear identification example, and inserted additional explanations to both examples. I've also changed one logical operation that prevented the Simulink implementation of the LWR-RD block to work with later versions of matlab.
