Variables:
FFT1dC fft;

FFT1dC ifft;

Methods:
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.
