<A HREF="../Vec/VecSetValuesLocal.html#VecSetValuesLocal">VecSetValuesLocal</A>() sets x[ix[i]] = y[i], for i=0,...,ni-1.

Calls to <A HREF="../Vec/VecSetValues.html#VecSetValues">VecSetValues</A>() with the <A HREF="../Sys/INSERT_VALUES.html#INSERT_VALUES">INSERT_VALUES</A> and <A HREF="../Sys/ADD_VALUES.html#ADD_VALUES">ADD_VALUES</A>

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/VecSetValuesLocal.html#VecSetValuesLocal">VecSetValuesLocal</A>() have been completed.
