@memoly

This example you are showing here seems to me to be a legitimate 3^3 Kautz sequence. Could you explain why you've identified these particular substrings as incorrect?

The condition of the Kautz sequence is not that there be no repeated characters in a substring (in your case, each set of 3), rather that the sequence simply not contain any *consecutive* repeats of the same character.

In its current form, no, there is no way to force it to generate all possible 4^2 sequences short of exhaustively running the function in a while loop and checking for unique results until all 16 are generated (not particularly efficient, to put it mildly).

28 Jun 2013 Oscillator and Signal Generator A simple command-line function for generating standard waveforms, click trains and noise bursts. Author: W. Owen Brimijoin

Oops.. my mistake, "chirp.m" is only included in the Signal Processing toolbox! I have updated the function to include simple linear and logarithmic sweep options. For these you need to provide a [start stop] vector of frequencies.

To the list of signal options, I have also added brown noise (1/f^2) and grey noise. Mind you, it's a generic grey (ISO Equal-Loudness at 60 phons), since *true* grey noise must be custom defined to match each listener's psychoacoustic loudness contour.

The updated version has been submitted and should pop up soon.

I am so glad you find this submission helpful, Deborah. Excellent suggestions, I will certainly add more noise forms as soon as I can compute the best filter coefficients I can. Watch this space for grey noise and brown noise, among others.

I am, however, hesitant to add support for frequency sweeps because I think it would complicate the currently simple input argument structure. What's more, there is the built-in Matlab 'chirp.m' function that does a bang-up job of making fm signals!

For the example sequence generated like : 3 1 3 2 1 2 1 3 1 2 3 2

But is that correct?

Using this code am i able to generate all debruijn sequences?........for example for n=4 and k=2,there are 16 debruijn sequences.
