KSPNormType#
Norm that is passed in the Krylov convergence test routines.
Synopsis#
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()

this must match petsc/finclude/petscksp.h
