Sorry, I thought this was clear. when you type sage: a=x+x+1 sage: a 2*x + 1
If I understood correctly, the simplification of x+x by 2*x is done by maxima in the background. I f x is here much more complicated (or if the expression itself is complicated), the simplification process can become lengthy and even crash maxima. So my question was : is this possible that when I ask a in the second line above, that the answer would be x+x+1 Sorry for the trouble Nicolas On 23 juin, 11:19, William Stein <wst...@gmail.com> wrote: > On Tue, Jun 23, 2009 at 9:40 AM, Nicolas<nicolas.fresseng...@gmail.com> wrote: > > > I am in the writing of a program that deals with rather lengthy > > symbolic expressions involving unknown functions and differentiation. > > When running commands like derivatives, it seems that maxima > > automatically runs into place to simplify the obtained expressions. > > (This is consistent with the documentation) > > > In interactive sessions, this is perfectly good, but for my > > application, it has two major problems : > > - things are slowed down a lot because maxima tries to simplify long > > expressions which cannot be much simplified > > - worse : maxima often crashes which renders the whole program > > difficult to use > > > My solution would be to disable maxima automated simplification but I > > cannot figure out if this is possible in sage or how to do it (I am > > using sage.4.0.1 on Fedora 10) > > Please provide a much more precise example than what you've given > above (which is no examples at all). > > -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
