sp_convergence() [1/2]

SRDef syten::Krylov::SolverPolicies::Eigen::sp_convergence ( DenseTensor< 2, SDef >  mat, SRDef &  evalue  )

inline

Tests convergence by calculating the overlap between the last-iteration result and the current result.

Calculates coefficients, so has to be called before sp_result().
