This was my first impulse until I saw that the syntax and the actually
implemented methods vary considerably inside scipy.sparse (different

Before I code around all of that, I would like to to see, which
functionality is really provided by which matrix class.

Do you know where to find an overview (some docs)? Currently, I stumble
upon unimplemented things in my unit tests and figure out what is going
on after reading the sparse code :-(
