Detailed Description

template<Real R>
struct uni20::linalg::LuConditionResult< R >

Reciprocal condition estimate, present only on numerical success.

Estimates 1/(norm(A)*norm(inv(A))) in the stated norm, at factor precision. It is not an error bound. Zero may indicate underflow or an unusably ill-conditioned matrix; it is a successful estimate.
