Detailed Description

template<Real R, std::size_t N = 1>
struct uni20::tanh_sinh_options< R, N >

Explicit precision, component tolerances and work limits for tanh-sinh quadrature.

Convergence uses max(absolute_tolerance[j], relative_tolerance*abs(value[j])). endpoint_power controls the transformed cutoff -endpoint_power*log(epsilon)+4; increasing it resolves stronger endpoint singularities at additional cost.
