Fwd: [sage-combinat-devel] Default basis ring for ambient space

2012-05-08 Thread Christian Stump
Hi Viviane, This type of thing just broke my entire patch on multivariate polynomials. I had to fix it by changing the field to ZZ or QQ but I wonder why the default field has been changed... sorry for that! the reason is that I implemented non-crystallographic root systems and reflection

Thanks for your quick reply! What version of Sage are you using? 5.0.rc0 You just need to edit that file (plot/plot.py) and make that change (delete the EMBEDDED_MODE line, and replace it with the from sage.misc line). You'll then need to apply the second patch: * go to

Hi Simon, Removing the offending __richcmp__ in FreeModuleElement seems to solve the problem once for all for all rings but introduce a lot of other problems. What other problems emerge? Actually, I was wrong saying that this solves the problem. The result is much faster but
