num::debug::probe_inner

Defined in header <algebra/debug.hpp>

template <class VectorType>
num::scalar_t<VectorType> probe_inner(const VectorType &x, const VectorType &y);

Inner product \(\langle x,y \rangle = \sum_i \overline{x_i} y_i\), through the type's own inner, so a probe exercises the shipped implementation.
