Detailed Description

Calculation of autocorrelation (and crosscorrelation) coefficients.

crosscorr() can be made available at short notice if required, it performs like autocorr() but for crosscorrelation coeffients.

[autocorr]
ncorr <nr>
Autocorrelation 0 .. ncorr will be calculated, default 0.
