[sage-devel] view() behaviour for Greek alphabet named variable or function

2009-03-23 Thread Golam Mortuza Hossain
Hi, It seems view() function behaves differently for Greek alphabet depending on whether they are defined as a variable or a function. For example, when I try var('alpha'); view(alpha) It gives nicely formatted latex

Hi, I've been doing some work on getting Sage-3.4 to work natively on FreeBSD and I've reached the point where I can compile sage-3.4 on FreeBSD-8/amd64 (using gcc/g++/gfortran 4.3) and get it to start. I have a patchset (1131 lines so far) and instructions if anyone else is interested (or if

Nice and interesting article on everything2.com about free maths software, a presentation by wolfram about mathematica and thoughts about the reason, why mathematica is still tolerated. Link to Sage included ;) http://everything2.com/title/mathematica%20and%20free%20software H

People, I'm really glad about having brought this discussion to a reasonably interesting level. From now on, I can't give any other comment (I can't deal with code so specific issues), but I'd like to hear those coming from the mantainers of SAGE. As far as I'm concerned, I was trying to get the

Robert, thank you very much for clarifying this. Could you please point us to some examples (if documentation is not that good) for the improved laplace transform? I strongly stress that having good examples about code use for engineers would be SO MUCH appreciated. Do you think that wiki

Hi, would it be possible to make the notebook files clickable in the following sense: If I have a file test.sws at /user/Documents/mySAGEfiles that I click then SAGE opens a new session by opening up a notebook server using the files at /user/ Documents/mySAGEfiles. This might even be done with
