KSPNormType

Norm that is passed in the Krylov convergence test routines.

typedef enum {KSP_NORM_DEFAULT = -1,KSP_NORM_NONE = 0,KSP_NORM_PRECONDITIONED = 1,KSP_NORM_UNPRECONDITIONED = 2,KSP_NORM_NATURAL = 3} KSPNormType;

Each solver only supports a subset of these and some may support different ones depending on left or right preconditioning, see KSPSetPCSide()
