Thanks (to both responders) for pointing in a helpful direction. I've
located two sparse matrix libraries (SparseLib++ and
SparseMatrixToolkit) which provide some of the ideas I'm looking for.
As you mentioned, Matlab seems to provide a very straightforward
sparse matrix storage scheme much like I'm looking for, so I'm going
to look into whether they provide any information on the low-level
coding of their sparse matrix routines....
