PetscDataType
Used for handling different basic data types.
Synopsis
typedef enum {PETSC_DATATYPE_UNKNOWN = 0,
PETSC_DOUBLE = 1, PETSC_COMPLEX = 2, PETSC_LONG = 3, PETSC_SHORT = 4, PETSC_FLOAT = 5,
PETSC_CHAR = 6, PETSC_BIT_LOGICAL = 7, PETSC_ENUM = 8, PETSC_BOOL = 9, PETSC___FLOAT128 = 10,
PETSC_OBJECT = 11, PETSC_FUNCTION = 12, PETSC_STRING = 13, PETSC___FP16 = 14, PETSC_STRUCT = 15,
PETSC_INT = 16, PETSC_INT64 = 17} PetscDataType;
Notes
Use of this should be avoided if one can directly use MPI_Datatype instead.
Developer comment
It would be nice if we could always just use MPI Datatypes, why can we not?
If you change any values in PetscDatatype make sure you update their usage in
share/petsc/matlab/PetscBagRead.m
