Prev: max value of two expressions

Hi,

I've started working with crosscorr(times1,times2), and am wondering how do I know which is the time series that is kept fixed, and which one is moved by the different possible lags?

I am somewhat naively expeting that the first input, in this case times1, is the one kept fixed, and the second input, in this case times2, is the one that is iteratively shifted with the different lags.

If anyone knows the answer to this issue, please share it with me

Simulate a signal, then shift the signal and measuring the correlation shift. You should be able to work out which way the shift is.
