I quite agree with you. Of course there are some sources of
documentation but a central source
like a complete and pdf-based manual would simplify matters.
Moreover scipy could benifit from supporting features which are rarely
in other numerical packages (e.g.sparse matrices, large scale
eigenproblems, to name a few)
(I am aware of the fact, that there is no all-in-one device suitable for
Lust but not least some kind of redundance in developing numerical
packages is visible
(at least from my point of view). Competition is helpful, but
why can't I see an effort to focus on a few but well developed packages.
BTW, the installation of scipy is not at all the problem.
Many thanks to all the developers of scipy.
