Definition value.hpp:61
nk::optim::fminsearch
Value fminsearch(FnHandle fn, Span< const double > x0, double tol, std::pmr::memory_resource *mr=nullptr)
Multi-dimensional unconstrained minimisation (x = fminsearch(fn, x0, tol)).
nk::optim::fminbnd
Value fminbnd(FnHandle fn, double lo, double hi, double tol, std::pmr::memory_resource *mr=nullptr)
Bounded scalar minimisation (x = fminbnd(fn, lo, hi, tol)).
nk::optim::fzero
Value fzero(FnHandle fn, double x0, std::pmr::memory_resource *mr=nullptr)
Scalar root-finder, initial-guess form (x = fzero(fn, x0)).
