400    #include <petscvec.h>
401    PetscErrorCode VecSetValueLocal(Vec v,PetscInt row,PetscScalar value, InsertMode mode);
402 
403    Not Collective
404 
405    Input Parameters:
406 +  v - the vector
407 .  row - the row location of the entry
408 .  value - the value to insert
409 -  mode - either INSERT_VALUES or ADD_VALUES
410 
411    Notes:
412    For efficiency one should use VecSetValues() and set several or
413    many values simultaneously if possible.
414 
415    These values may be cached, so VecAssemblyBegin() and VecAssemblyEnd()
416    MUST be called after all calls to VecSetValues() have been completed.
417 
418    VecSetValues() uses 0-based indices in Fortran as well as in C.
