       Function that evaluates if the approximate triplet has converged.
       If NULL, it is used the default convergence criteria (see |Seps|).
 
       :param sval: the approximate singular value to evaluate.
       :param leftsvec: one dimensional array of size |SmLocal| containing the approximate left singular vector; it can be NULL.
       :param rightsvec: one dimensional array of size |SnLocal| containing the approximate right singular vector; it can be NULL.
-      :param resNorm: the norm of the residual vector.
+      :param rNorm: the norm of the residual vector.
+      :param method: current eigenvalue problem being solved, either,  :c:enumerator:`primme_svds_normalequations` or  :c:enumerator:`primme_svds_augmented`.
       :param isconv: (output) the function sets zero if the pair is not converged and non zero otherwise.
       :param primme_svds: parameters structure.
       :param ierr: output error code; if it is set to non-zero, the current call to PRIMME will stop.
