backsolve... --> class()es for special matrices ?
...()..
Well, we (R core) have discussed matrix classes months and years ago..
and haven't really started doing anything about it.
I think we then agreed to follow Splus' Matrix library
and use class "Matrix"
(and classes inheriting from "Matrix", i.e.
class == c("specialMatrix", "Matrix")
).
If we really go into this, then
we'd probably want to use the SAME class names that S-plus' library(Matrix)
is using.
Also, I remember that people (on the old R-testers list?)
very much desired to have 1-column or 1-row matrices instead of vectors
when work...
