Hi Dirk,

Thanks for your suggestion - I had thought of doing that but it requires 
tracking the versions of SuiteSparse used by Matrix, which means extra 
maintenance work. OTOH maybe updates are rare enough that it's not worth 
worrying about. It'd be nice if Matrix could expose more of SuiteSparse, 
though, I'm sure I'm not the only one who needs that stuff.
