Correlation1dC::Correlation1dC(IntT) Correlation1dC::Apply(const Array1dC &,const Array1dC &) Correlation1dC::AutoCorrelation(const Array1dC &)

Correlation1dC(IntT size)

Constructor.
Give the size of arrays to correlate.

Array1dC<RealT> Apply(const Array1dC<RealT> & d1,const Array1dC<RealT> & d2)

Return the correlation of signals d1 and d2.
This uses FFT to caculate the correlation between d1 and d2. both d1 and d2 must have the same length.

Array1dC<RealT> AutoCorrelation(const Array1dC<RealT> & d1)

Return the auto correlation signals d1.
This uses FFT to caculate the correlation d1 and itself.
