C++ (Cpp) transTableSetup Examples

Example #1

File: mixfft.cpp Project: FreeSivan/drawfreq

void xiami_fft(int n, double xRe[], double xIm[],
                double yRe[], double yIm[])
{
    int   sofarRadix[maxFactorCount], 
          actualRadix[maxFactorCount], 
          remainRadix[maxFactorCount];
    int   nFactor;
    int   count;

    pi = 4*atan(float(1));    

    transTableSetup(sofarRadix, actualRadix, remainRadix, &nFactor, &n);
    permute(n, nFactor, actualRadix, remainRadix, xRe, xIm, yRe, yIm);

    for (count=1; count<=nFactor; count++)
      twiddleTransf(sofarRadix[count], actualRadix[count], remainRadix[count], 
                    yRe, yIm);
}   /* fft */

Example #2

File: mixfft.hpp Project: EQ4/vasp

 MixFFT(int _n):
     n(_n)
 {
     transTableSetup(sofarRadix, actualRadix, remainRadix, &nFactor, &n);
 }   /* fft */

Example #3

File: mixfft.c Project: kerkomen/stereogene

void initFFT(int n){
	fftLength=n;
	transTableSetup(sofarRadix, actualRadix, remainRadix, &nFactor, n);
}
