Felix, What do you mean by "cross correlate signals?" What kind of signals do you have, are they related? If you already have all of the values used in the function and are just concerned on how to implement this function into LabVIEW, you can use one of the Mathematics>>Formula VIs.

Yes, the 5 signals are related in the sense that they are similar but time shifted. Using the cross correlation I want to calculate the thime shift. The problem is that we have a lot of data. We sample 25 channels with 50 kHz in total. I was concerned about the velocity of the vi and a simple handling.
