[sage-devel] 5.2 does not compile, breaks in atlas

Hi, Just tried to compile 5.2 on a RHEL 5.8 system on the latest HP ProLiant ml110 G7 system and the compile breaks while trying to configure and compile atlas. I have downloaded the latest version of atlas3.10.0.tar.bz2 and that compiles out of the box on its own. The original version of atlas3.

[sage-devel] Re: experiment with a new version of the SageTeX package

Hi, First of all let me say that I am currently writing a math text book where I am using a lot of sagetex and I think it is a great package! Having said that as a "user" I am a bit concerned that the syntax of sagetex is going to change if I want to publish the latex sources or describe examples

[sage-devel] Failure to calculate ln(factorial(171))

Hi, If you copy and paste the following into a command line sage session print ln(factorial(171)) print ln(factorial(171).n(100)) print ln(factorial(171)).n(100) print ln(factorial(171)*1.0) you get: sage: print ln(factorial(171)) log(124101807021766782342484052410310399261660557750169318538895

[sage-devel] Implementation of Zeilberger and similar algorthms?

Below is a python script that implements the above and sets environment variables for parallel compiles. Just save the script to makesage.py (say) in the sage root dir and run it via python makesage.py -j8 It reduced the sage-4.0.2 compile to 1hour 51 minutes on a dual quad AMD 2GHz machine. --

Hi Dan, Thanks for reviewing the code. I have included your suggestions and I have done a spell check on the file now and will submit the updated version to trac once I get an account. (Michael?) As a side remark concerning the prec argument, it is passed straight into the sqrt() functions used

Hi Ondrej, No, I have not come round to publishing it yet in Comput. Phys. Commun. or some similar journal. The thought has occured to me that one could use the index functions for the 3j, 6j, and Gaunt coefficients for a much simpler storage scheme in python by using the index as a key for a d

[sage-devel] Wigner 3j, 6j, 9j, Clebsch-Gordan, Racah and Gaunt coefficients

Hi, I have coded some routines that calculate Wigner 3j, 6j, 9j, Clebsch- Gordan, Racah and Gaunt coefficients (integrals over 3 spherical harmonics) exactly. It is all in a single python file with doc tests. If I am not mistaken then Sage currently does not have such functionality and I think it
