ResidualNormStopCrit

class probnum.linalg.solvers.stopping_criteria.ResidualNormStopCrit(atol=1e-05, rtol=1e-05)

Bases: probnum.linalg.solvers.stopping_criteria.LinearSolverStopCrit

Residual stopping criterion.

Terminate when the euclidean norm of the residual \(r_{i} = A x_{i} - b\) is sufficiently small, i.e. if it satisfies \(\lVert r_i \rVert_2 \leq \max( \text{atol}, \text{rtol} \lVert b \rVert_2)\).

Parameters
