Detailed Description

template<Real R>
struct uni20::krylov::GmresOperatorEstimates< R >

Optional properties of the original operator in the vector space's 2-norm.

These describe the operator actually solved, including any gauge constraint, rather than a preconditioner or projected Hessenberg matrix. Supplying them incurs no additional operator applications. Inverse norms and condition numbers assume an invertible operator.
