<A HREF="../Vec/VecSetValuesBlockedLocal.html#VecSetValuesBlockedLocal">VecSetValuesBlockedLocal</A>() sets x[bs*ix[i]+j] = y[bs*i+j],
for j=0,..bs-1, for i=0,...,ni-1, where bs has been set with <A HREF="../Vec/VecSetBlockSize.html#VecSetBlockSize">VecSetBlockSize</A>().
<P>
Calls to <A HREF="../Vec/VecSetValuesBlockedLocal.html#VecSetValuesBlockedLocal">VecSetValuesBlockedLocal</A>() with the INSERT_VALUES and ADD_VALUES
options cannot be mixed without intervening calls to the assembly
routines.
<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/VecSetValuesBlockedLocal.html#VecSetValuesBlockedLocal">VecSetValuesBlockedLocal</A>() have been completed.
<P>
<A HREF="../Vec/VecSetValuesBlockedLocal.html#VecSetValuesBlockedLocal">VecSetValuesBlockedLocal</A>() uses 0-based indices in Fortran as well as in C.
