◆ operator()() [1/3]

template<class T >
bool ComplexLess< T >::operator() ( const complex< T > &  x,
const complex< T > &  y 
) const
inline

Comparison in terms of magnitude of complex number.

62  {
63  //Return the order in terms of magnitude if they are not equal
64  //Include a tolerance to avoid processor specific ordering
65  if(std::abs(std::abs(x) - std::abs(y)) > 1.0e-10 )
66  {return std::abs(x) < std::abs(y);}
67  //Otherwise sort on real part, again with a tolerance
68  else if(std::abs(x.real() - y.real()) > 1.0e-10)
69  {return x.real() < y.real();}
70  //Otherwise sort on imaginary part
71  else
72  {return x.imag() < y.imag();}
73  }
