beim Versuch, die folgende Funktion in meinem Programm auszuführen:
//iterDelayEst.cpp
#include <complex>
#include "binFreq.cpp"
#include <valarray>
typedef std::complex<double> Complex;
typedef std::valarray<Complex> CArray;
double iterDelayEst(int n,CArray& x, CArray& x2)
{
/****************************constants*********************/
//exit if uncertainty below threshold
double thr_samples = 1e-7;
//exit after fixed number of iterations
double nIter = 25;
fft(x);
fft(x2);
//frequency domain representation of signals
std::vector<double> tau;
auto f = binFreq(n);
std::vector<double> e;
int j;
for (j = 0 ; j < n ; j++){
auto nf1= ((x*std::conj(x) * (x2*std::conj(x2));
nf1 +=nf1;
auto nf2 =std::sqrt(nf1);
auto nf =nf2/(double)n;
}
}
I denke, es kann mit conj Argumenttyp verwandt sein, aber ich kann herausfinden, wie man es löst. Danke für die Hilfe und fühle mich frei, mich zu bitten, alles zu klären.
Dank Piotr, scheint es zu funktionieren !!!! – Serge
