In instalatiopn guide you can find: SAGE_ATLAS_LIB - if you have an installation of ATLAS on your system and you want Sage to use it instead of building and installing its own version of ATLAS, set this variable to be the parent directory of your ATLAS installation: it should have a subdirectory l

Hi, I have a Dell 980 optiplex machine with i7 processor (8 core), 16GB RAM. I tried to install sage on it with OS: Centos 5.5. I tried both versions sage-4.6.2 and sage-4.5.2 and both crashed. It seems the problem is only with ATLAS, whatever that is: Attached is is a dump of what I got on the

Hi Jeffrey, I think you're working too hard to install Sage. For Mac, you just need to copy the "sage" folder from the installer disk to your "Applications" folder, and then open it and run the "sage" executable with Terminal. The same works for the sage app bundle. In either case, you should n

you might try using the zip command. If you use the * operator with zip it will unpack the elements into the individual variables Sys, Dia, Pulse =zip(*mesures) mesures.append([181,88,58]) Sys[-1],Dia[-1],Pulse[-1] of course you can use zip to go the other way too: mesures = zip(Sys, Dia, Pulse)

Hello, i was working with real functions in real coefficients. I was doing some test to be sure it was all always real (without imaginary part), and i ask Sage to solve this: var('x',domain=RR); solve([imag(x)==0,imag(sqrt(-x^2-1))==0],x); and it answered me: [[x == -I], [x == I]] I would under

Hi, I can't tell whether you've had any experience with Sage before, so I'll assume not. On Mar 28, 2011, at 19:43 , Jeffrey wrote: > Hi. > I'm working on a Mac G5 & trying to install Sage. Darwin needs > packages installed in site-packages within Python folders in > Frameworks. But the Sage bi
