Detailed Description

template<class abs_f>
struct tlapack::IamaxOpts< abs_f >

Options for iamax.

Initialize using a lambda function (C++17 or higher):

IamaxOpts opts( [](const T& x) { return my_abs(x); } );

or using a functor:

struct abs_f {
   constexpr real_type<T> operator()(const T& x) const {
      return my_abs(x);
  }
};
abs_f absf;
IamaxOpts<abs_f> opts( absf );
