472    PetscErrorCode VecSetValueLocal(Vec v,PetscInt row,PetscScalar value, InsertMode mode);
473 
474    Not Collective
475 
476    Input Parameters:
477 +  v - the vector
478 .  row - the row location of the entry
479 .  value - the value to insert
480 -  mode - either `INSERT_VALUES` or `ADD_VALUES`
481 
482    Notes:
483    For efficiency one should use `VecSetValues()` and set several or
484    many values simultaneously if possible.
485 
486    These values may be cached, so `VecAssemblyBegin()` and `VecAssemblyEnd()`
487    MUST be called after all calls to `VecSetValues()` have been completed.
488 
489    `VecSetValues()` uses 0-based indices in Fortran as well as in C.
