template<class Function , typename std::enable_if_t< std::is_invocable_r_v< Scalar, Function, Scalar > > ...>
- Note
- This version overloaded to not require arguments passed in for function evaluation counts or error estimates.
- Parameters
-
| f | the integrand (invocable with a single scalar) |
| a | lower integral bound |
| b | upper integral bound |
| targetAbsoluteError | desired absolute error in the result |
- Returns
- The value of the integral.
