[sage-support] Problem with polynomial factoring?

Hi, I get this error when I try to factor a polynomial. I gather that it seems to be something wrong with Singular? I don't really know what I'm doing, but I think I set it up correctly. I upgraded to 2.10 yesterday or so, but this problem happened with the previous version I had. Thanks! -Alde

[sage-support] Taylor series of a matrix

I would like to take the Taylor series of a matrix. But I find I can't even put a Taylor polynomial into a matrix without its being simplified. sage: f=-x/(2*x-4); f -x/(2*x - 4) sage: g=taylor(f,x,1,1); g 1/2 + x - 1 sage: matrix(1,[g]) [x - 1/2] sage: m=matrix(1,[f]); m [-x/(2*x - 4)] sage: m.

I assume you did sage -i gap_packages-4.4.10_3 I tested this on an intell macbook and a linux box running ubuntu fiesty fawn and it worked fine on both. First, it looks like the GAP packages were installed fine but nauty wasn't compiled (which is distributed with grape, a graph theory package). I

[sage-support] 3d plotting on os x 10.4, ppc

Hi, I've had trouble getting the 3d plotting to work on my aging ppc mac laptop. I tried upgrading java, but that seemed to actually make things worse. If anyone out there has it working nicely, what version of java are you using? (Currently I get a black square and nothing else, even if I wai

[sage-support] DegreeSequence questions

Hi Robert, Jason, et al. I've got some questions about the functioning of the various graphs.DegreeSequence functions. First, just something I'm not familiar with - what is the difference between DegreeSequence, DegreeSequenceExpected, and DegreeSequenceTree? I thought the first and last genera

[sage-support] Sage 2.10.1.rc3 released!

Here we go: Sage 2.10.1.rc3 is hopefully the next to last rc. The release is planned in the next 24 hours. We finally fixed the GNUTLS issues, elliptic curve improvements (#740), some Solaris build issues and various bug fixes. What needs to be done before the release is #1968 (a security fix), al

Hi William, thanks for your help. The file worked perfectly fine! Kudos to the program, I'm just starting to use it and already it seems REALLY powerful! Cheers Matthias On Jan 29, 10:48 am, "William Stein" <[EMAIL PROTECTED]> wrote: > On Jan 29, 2008 3:57 AM, Reineke <[EMAIL PROTECTED]> wro
