Personal Profile:

I am one the developers for the WFDB Toolbox for MATLAB and Octave. This toolbox gives users direct access to over 50 databases (over 3 TB of physiologic signals including ECG, EEG, EMG, fetal ECG, PLETH, ABP, and more). Most of these databases are also accompanied by meta-data such as expert annotations of physiologically relevant events. These can include, for example, cardiologist annotations on ECGs for classifying different arrythmias, or sleep expert annoations on EEG for segmenting different sleep stages. The project is open-source and web page is located at: http://physionet.org/physiotools/matlab/wfdb-app-matlab/

@Smith, send me an email with the exact error message (if any), steps, and the matlab version that you are using. thanks.

@Chan, the data was artificially generated a long time ago. It was simple 2D exponential decay.

04 Jul 2014 Gradient Adaptive Laguerre Lattice Filter Single pole order recursive gradient adaptive lattice filter Author: Ikaro Silva Behnam

ooops, I am sorry. I did a mistake. The code to which I pointed is correct.
I cannot delete my comment. If you can please do it.

I think there is a bug in the code:
Lines 134-143 should change from

for n=1:N

f(1)=alpha*b_old(1) + sqrt(1-alpha^2)*x(n);
b(1)=f(1);
Q(1) = beta.*Q(1) + b(1).^2;
err(n,1)=d(n);
bt_old=bt;
b_old=b;

TO .......

for n=1:N

bt_old=bt;
b_old=b;
f(1)=alpha*b_old(1) + sqrt(1-alpha^2)*x(n);
b(1)=f(1);
Q(1) = beta.*Q(1) + b(1).^2;
err(n,1)=d(n);

I had downloaded the code, and I have tried many times.But I don't konw how could I get the same result as you did. Can you help me?
