Detailed Description

template<typename R, typename ... Args>
class chebyshev::prec::estimate_options< R, Args >

A structure holding the options for precision estimation.

Constructor & Destructor Documentation

◆ estimate_options()

template<typename R , typename ... Args>
chebyshev::prec::estimate_options< R, Args >::estimate_options ( )
inline

Construct estimate options with all default values.

Note
The estimator and domain must be set to correctly use the options for test cases.
