MatInfo#
Context of matrix information, used with MatGetInfo()
Synopsis#
typedef struct {
PetscLogDouble block_size; /* block size */
PetscLogDouble nz_allocated, nz_used, nz_unneeded; /* number of nonzeros */
PetscLogDouble memory; /* memory allocated */
PetscLogDouble assemblies; /* number of matrix assemblies called */
PetscLogDouble mallocs; /* number of mallocs during MatSetValues() */
PetscLogDouble fill_ratio_given, fill_ratio_needed; /* fill ratio for LU/ILU */
PetscLogDouble factor_mallocs; /* number of mallocs during factorization */
} MatInfo;
Fortran Note#
Information is stored as a double-precision array of dimension MAT_INFO_SIZE
