PETSC_DETERMINE#
standard way of passing an integer or floating point parameter to indicate PETSc should determine an appropriate value
Example Usage#
VecSetSizes(ksp, 10, PETSC_DETERMINE);
indicates that the local size of the vector is 10 and the global size will be automatically summing up all the local sizes.
Note#
Same as PETSC_DECIDE
Fortran Note#
Use PETSC_DETERMINE_INTEGER or PETSC_DETERMINE_REAL.
Developer Note#
I would like to use const PetscInt PETSC_DETERMINE = PETSC_DECIDE; but for
some reason this is not allowed by the standard even though PETSC_DECIDE is a constant value.
