For efficiency one should use <A HREF="../Vec/VecSetValues.html#VecSetValues">VecSetValues</A>() and set several or
many values simultaneously if possible.
<P>
These values may be cached, so <A HREF="../Vec/VecAssemblyBegin.html#VecAssemblyBegin">VecAssemblyBegin</A>() and <A HREF="../Vec/VecAssemblyEnd.html#VecAssemblyEnd">VecAssemblyEnd</A>()
MUST be called after all calls to <A HREF="../Vec/VecSetValues.html#VecSetValues">VecSetValues</A>() have been completed.
<P>
<A HREF="../Vec/VecSetValues.html#VecSetValues">VecSetValues</A>() uses 0-based indices in Fortran as well as in C.
