hi, is there a command of sequence alignment for any sequence generally ? I did not mean swalign or nwalign, these just for biological sequences. if not are there anyone wrote a code of sequence alignment for non biological sequences in matlab?
thanks

thanks walter, i will see the link
sven , I mean any sequence of integers or characters.
There is algorithms of seq. alignment but designed for DNA or protein sequences.
I hope to find for general seq.
thanks

What sequence? If you mean any two numerical sequences which are correlated. Their alignment can be done by using cross correlation and finding where the peak is in terms of the delay, then shifting one of the sequence by the delay.
xcorr = ifft(fft(signalA).*conj(fft(signalB));
delay = find((xcorr==max(xcorr))==1);
AlignedA = circshift(signalA,1-delay);
