[sage-support] Index of Reference Manual Does Not Display Properly

In three different Mac browsers (Safari, Camino, Firefox) the two- column display of an index page such as http://www.sagemath.org/doc/reference/genindex-A.html has a white background when first displayed, but scroll to the right and the new area has a dark blue background. This makes reading

A related question: is it possible to catch an exception if there is a time out? I think there should be. The timeout process should raise an exception which can be catch. Right now, one can catch that it sends back a string 'NO DATA (timed out)' rather than a result. So the following

Hi, I use ZZ(ss).factor(proof=False,limit=10^5). By changing 'limit' you limit the search. 2^26 * 3^30 * 5^15 * 7^5 * 13^5 * 23^2 * 29 * 37 * 967 * 100231435706561580153005984524922236635721822683010490144527758096287118\ 468921220756478157058125901560872523532972896397 This can be combined

[sage-support] The Milestone field in Trac Tickets

2010-07-19 Thread Mike Witt
I'm curious about the intent behind the Milestone field in Trac tickets. It appears (at least for tickets I've been interested in) that this field is always set to whatever the next coming release is. Then, after that release is done, the milestone is (automatically?) bumped up to the next

[sage-support] Symmetric Functions itensor

2010-07-19 Thread vasu
Hi all I have been using the inner tensor product in the Schur basis. My question is : a) Is it just my computer or is this way slower than Stembridge's SF package ? For example, SF computes s[14,14].itensor(s[14,13,1]) in no time . But it seems to take quite a lot of time on Sage. I have 4

2010-07-19 Thread Marshall Hampton
Using Polyhedron as you are doing is the correct way to compute convex hulls in Sage. If your vertices are integral, then you could also try using the LatticePolytope class. LatticePolytope uses PALP instead of cddlib, and so might be faster for some inputs. I have meant for a long time to make

2010-07-19 Thread Marshall Hampton
Sadly this is not possible now but its something we should have. I would like to someday add (or have someone else add) a beneath-and- beyond convex hull method to Sage; once we have that it would be pretty easy to add a method to the Polyhedron class that could take a vertex as an input and add
