I've tried to build sage-4.3.2 on Solaris 10 using gcc 4.4.3 (the latest version). It is complaining about some code in NTL, specicially the use of 'if' and 'define' include/NTL/config.h. I'm not a C++ programmer. It is normal to put 'if' and 'define' on two lines like this below? #if /*

Hi folks, I'm just re-posting mhampton's question here with the above subject, so it would be picked up by the relevant maintainers of GLPK. On Fri, Feb 12, 2010 at 11:55 AM, mhampton wrote: > I haven't seen it matter with 4ti2 or your sandpiles stuff, but there > is a much more recent glpk pack

You might check out the syntax and semantics for part() and inpart() in Maxima, and be sure to note the difference. The notation for selecting parts in Mathematica is something like x[[1]]. note in particular that in Maxima, x/y internally looks more like x * y^(-1), so the main operator is

I haven't seen it matter with 4ti2 or your sandpiles stuff, but there is a much more recent glpk package, glpk-4.38.p4, which is probably better to use. General question: is there any reason that the experimental glpk-4.9 spkg still exists at all? If not it should be removed. -Marshall On Feb 1

Hi, I'm forwarding this to the Macaulay2 list, since at Sage Days 14 (?), Dan Grayson's project was to embed Sage into Macaulay2. He was extremely successful at doing this, and showed us some cool demos as a result. Maybe he can make some comments. William On Thu, Feb 11, 2010 at 4:28 PM, Bur

[sage-devel] complex and real infinity in Sage

2010-02-11 Thread ma...@mendelu.cz
Dear Sage Lenka Viskotova found a bug in evaluating limits in Sage. Evaluating limits via Maxima may return complex infinity or real ininity. Sage does not distinguish between them. As a consequence, limit(1/x,x=0) is wrong. I was not able to find report on this and thus reported this as http://t

Dear Nils, That's great, thanks! For some reason, I overlooked the utility of operands() when I was trying things out. This seems perfectly adequate for my purposes. The suggested extension of operands() to take a syntax like operands([0,1]) would be nice, too! +1 from me if this counts. You
