PETSC_DETERMINE#

standard way of passing an integer or floating point parameter to indicate PETSc should determine an appropriate value

Example Usage#

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.
