<LI>If the descriptor is in the build state, then the sparse matrix
|
|
must also be in the build state; the action of the routine is to
|
|
(implicitly) call <code>psb_cdins</code> to add entries to the sparsity
|
|
pattern; each sparse matrix entry implicitly defines a graph edge,
|
|
that is passed to the descriptor routine for the appropriate

processing;

the sparse matrix that would generate additional communication
