Hi folks, It's been about a year now since we have any updates to the Sphinx package. Sphinx has now reached version 1.0.4 and ticket #10118 [1] attempts to upgrade to that upstream version. Sphinx affects every file in the Sage library and the SageNB package that has docstrings. It is crucial

[sage-devel] Executing a large script.

I was trying to execute a large script, which I had generated automatically with a view to testing Sage at integrating and differentiating random polynomials. The script looks a bit like this, but has many entries, with each polynomial generated randomly. f1=+2-2*x+2*x^2+2*x^3+4*x^4-1*x^5+3*x^6

[sage-devel] Bad result of integrate from maxima, are those documented/listed in some place?

2010-11-08 Thread Andrzej Giniewicz
Hi, I recently found an integral that returns bad result. I already reported it to Maxima tracker, but before they fix it, is there some place (ticket?) in which such buggy integrals, limits, etc are listed so when bugs are fixed upstream they can be doctested? For example I noticed that sage:

Dear all, I wanted to compute some good old Bessel functions, and came upon the following behavior. I did not want to open trac tickets for all of this, since I didn't know (apart from 1) whether this behavior is intentional or not. 1) Sage uses a function Bessel which does some input checking

At least historically, such errors often had their own Trac tickets for putting doctest patches when such things were fixed. I don't know if that is the best way, but it does at least call attention to the actual error, as opposed to subsuming it into a Maxima upgrade ticket. - kcrisman -- To

I suggest that if you are mostly doing integrals, that you just download the latest Maxima (I use it via wxmaxima), and not use it through Sage. Also it is possible to do some integrals with Mathematica, available in some form via the Wolfram Alpha web site, (free). -- To post to this group,
