Hi everybody,
Actually my question is simple and in the title... I need to cross-correlate two vector so I'd liked to get this function to do it.
Thanks in advance,
Virginie

conv(x(:),flipud(y(:)))
should be the same as xcorr(x,y) pretty much.

Its fairly easy to implement, or you can definitely find something on FEX that will work for you:
