Function Documentation

void box_mueller (  double &  r1, double &  r2 )  [inline]

return a random variable with 2d gaussian distribution

double chisq_2gf (  const vector< float > &  data, vector< double > &  centers, vector< double > &  widths, vector< double > &  amps, double &  dcconst, int  verbose = 0 )

function used in twogauss_fit

template<class T> void complex_cyclic_permutation (  vector< long >  axes, long  xshift, long  yshift, T *  data )

This isn't a particularly safe function... It cyclically permutes data by xshift and yshift. The zeroth element of the axes vector corresponds to the y direction, and the first element of the axes vector corresponds to the x direction

template<class T> void cyclic_permutation (  vector< long >  axes, long  xshift, long  yshift, T *  data )

This isn't a particularly safe function... It cyclically permutes data by xshift and yshift. The zeroth element of the axes vector corresponds to the y direction, and the first element of the axes vector corresponds to the x direction

template<class U, class V> void fit_straight_line (  const long &  nelems, const double *  x, const U *  y, const V *  wts, double &  slope, double &  sigsq_slope, double &  yintercept, double &  sigsq_yintercept, double &  chisq )

Modification of numerical recipes algorithm for fitting a straight line

void twogauss_fit (  const vector< float > &  data, vector< double > &  centers, vector< double > &  widths, vector< double > &  amps, double &  dcconst )

fit gaussians
