SVDStoppingCtx

Data structure (C struct) to hold additional information to be used in some stopping test functions.

Synopsis

struct _n_SVDStoppingCtx {
  PetscReal firstsv;    /* the value of the first converged singular value */
  PetscReal lastsv;     /* the value of the last converged singular value */
  PetscReal thres;      /* threshold set with SVDSetThreshold() */
  PetscBool threlative; /* threshold is relative */
  SVDWhich  which;      /* which singular values are being computed */
};
