[sage-devel] Sage days in Orsay

2008-07-12 Thread Nicolas M. Thiery
Dear Sage and *-Combinat developers, I have secured some preliminary funding from my university in France to organize some Sage days there (Orsay, 35 minutes by local train from downtown Paris). The idea is three fold: - Have a followup to Sage Days 10 in Nancy, surfing on its wave,

I can assure you that many mathematicians use mathematica in thier research; I used to. But one of the many appeals of Sage is that the source is open/checkable - I have had referrees mention that as desirable on some of my previous mathematica-based papers. In my opinion the gap between Sage an

This is called flamebait, and I am guessing thats why no one has responded yet. But its been in the back of my mind since I first read it yesterday, and here is what I have to say... I just kind of started following SAGE but the most obvious response to this sort of criticism is to point out tha

I looked through that log. All goes well until here: /home/bourba/tmp_sage/sage-3.0.4/local/lib/libntl.so: undefined reference to `.MASF71' which means that the problem is with linking with the NTL library. Did NTL build properly? John 2008/7/12 bourbabis <[EMAIL PROTECTED]>: > > Hello everyb

2008-07-12 Thread David Joyner
Possibly, this is not a bug in Ring. For the class of Piecewise functions, __mul__ is implemented in a way that allows you to multiply two elements in that class. If you try to multiply a piecewise times a rational (in that order) then it detects this and creats on the fly a piecewise function equ

Hi, I'm brand new to sage, just installed it on my mac, and was going through some of the examples and found a bug when I tried to multiply a piecewise function by a constant: sage: x = PolynomialRing(QQ, 'x').gen() sage: f = Piecewise([[(0,1),1*x^0]]) sage: r = f*2 sage: r = 2*f
