<A HREF="../Vec/VecSetValuesBlocked.html#VecSetValuesBlocked">VecSetValuesBlocked</A>() sets x[bs*ix[i]+j] = y[bs*i+j],
for j=0,...,bs, for i=0,...,ni-1. where bs was set with <A HREF="../Vec/VecSetBlockSize.html#VecSetBlockSize">VecSetBlockSize</A>().
<P>
Calls to <A HREF="../Vec/VecSetValuesBlocked.html#VecSetValuesBlocked">VecSetValuesBlocked</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>
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/VecSetValuesBlocked.html#VecSetValuesBlocked">VecSetValuesBlocked</A>() have been completed.
<P>
<A HREF="../Vec/VecSetValuesBlocked.html#VecSetValuesBlocked">VecSetValuesBlocked</A>() uses 0-based indices in Fortran as well as in C.
<P>
Negative indices may be passed in ix, these rows are
simply ignored. This allows easily inserting element load matrices
with homogeneous Dirchlet boundary conditions that you don't want represented
in the vector.
