Hello, I have just made some tests with the correl function of the "Numerical Recipes" (www.nr.com, http://library.lanl.gov/numerical/bookcpdf/c13-2.pdf). I am interessted in the autocorrelation (== both input sets are equal). When the input (1..8) is 0, 1, 0, 0, 1, 0, 0, 0 The Result is 2, 0, 0, 1, 0, 1, 0, 0 Using the given reordering the result should be interpreted as Source 0 1 0 0 1 0 0 0 Lag -3 -2 -1 0 +1 +2 +3 +4 Answer 1 0 0 2 0 0 1 0 Q: Could somebody confirm that this is correct? It seems correct for me, because in the source the two "1" have a distance of 3, so the result shows a correlation at +- 3. Thanks Ekkehard
