Thank you for your comments. As my appreciation for your kind encouragements, I am now preparing another, more elaborate, FxLMS example. Please wait for a couple of weeks. I wish you all the very best.

Very useful piece of code.
What I think is missing is the output of natural frequencies for the various modes in dimensional form.

According to the original reference, it seems to me that, if the line 349:

tmp=num2str(sqrt(tmp/I2I6)*handles.a^2,'%1.2f');

is subsituted by the following line:

tmp=num2str(sqrt(tmp/I2I6)*handles.a^2*sqrt(handles.B/handles.ps)/handles.a^2/2/pi,'%1.2f');

which is equivalent to

tmp=num2str(sqrt(tmp/I2I6)*sqrt(handles.B/handles.ps)/2/pi,'%1.2f');

then output frequencies are dimensional (in Hz).

It would therefore be very useful to have both outputs in the lower left listbox, i.e. nondimensional frequency and also dimensional (Hz or rad/s) frequency.

Bye,
Gabriele

I don't want simulation any more! Do any one here have any program which creates and cancels at least a single pure tone? ( u require a microphone to pickup error signal and two speakers to produce noise and anti noise. u have all of them in a PC.)
