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()
