MatFactorShiftType#
Type of numeric shift used for factorizations
Synopsis#
typedef enum {
  MAT_SHIFT_NONE,
  MAT_SHIFT_NONZERO,
  MAT_SHIFT_POSITIVE_DEFINITE,
  MAT_SHIFT_INBLOCKS
} MatFactorShiftType;
Values#
- MAT_SHIFT_NONE- do not shift the matrix diagonal entries
- MAT_SHIFT_NONZERO- shift the entries to be non-zero
- MAT_SHIFT_POSITIVE_DEFINITE- shift the entries to force the factorization to be positive definite
- MAT_SHIFT_INBLOCKS- only shift the factors inside the small dense diagonal blocks of the matrix, for example with- MATBAIJ
