Hi John,
Thanks for the reply, the suggestions and the examples. I've seen the
Factorization object and briefly thought of building a Spectrum
object, but thought it sounded like overkill. But maybe I can just
subclass Factorization and override the _repr_ method (or similar) to
print the spect

I vote a big +1 on one directory with both -- I think that'd be way easier.

At first glance, the mac os x download page looks like there are no
binaries.
Could we make the intel/powerpc split more obvious, or add
instructions, or make just one directory with both?

Thanks for posting these. I just pointed my office mate, who knows a
lot of maple but little sage, to them as a tutorial.

Harald, thanks for this post, I hadn't heard of this until now. I
don't think our group yet has a need to interface Sage and Matlab
(which everyone here uses), but should one arise and we wind up
integrating mlabwrap into Sage, we'll surely share with the community.

Dear sage-devel,

the University of Siena aimed at upper level undergraduates, graduate
students and interested professors. I created a bunch of worksheets for
these lessons, and thought that maybe some of you might find the

Hold on, I'm not complaining or offended! Everythin is properly
credited on the release tour, but in the email you listed 35 names
which did not include all the ones mentioned (and properly credited)

in the email -- but if you (

I think a useful thing to have in sage would be mutations of graphs
(which occur in the theory of cluster algebras by Fomin and
Zelevinski). Bernhard Keller has written a java applet (and
application) to do this which is widely used.
