[sage-support] sage won't compile on Arch Linux i686

Hello: I just began using sage and was very impressed with its capabilities. Unfortunately, almost as soon as I began using it, I found out the latest version won't compile on Arch Linux and some other distros. Details can be found at these links: http://trac.sagemath.org/sage_trac/ticket/11391

In some previous incarnation, where Sage used Maxima for things like this, your simplification happened. (%i1) 1/sqrt(5); 1 (%o1) --- sqrt(5) (%i2) sqrt(5)/5;

[sage-support] Simplification Issue Implicates Canonical Form

Hello sage-support, I'm a Sage newbie who just joined the group. Before I get to the meat of my post, I'd like to thank the open source math software community for all of your hard work! Nothing I say should be misinterpreted as a complaint. I have only admiration and gratitude. I ran into an

[sage-support] Fastest Lattice Reduction

I need to reduce a lattice of dimension 200 with its entries sizes are of size like 3000 bit. I use LLL(algorithm="fpLLL:fast") for faster lattice reduction. But it seems there is a problem in the function. Reduction is very bad. Is there any way to reduce this size of matrix efficiently? -- To

[sage-support] Re: Normal Distribution

Not sure what generating "integers" means, when drawing from a normal, but if you just want to draw random numbers, the following should do it: NV001 = RealDistribution('gaussian',sqrt(0.1)) #N(0,0.1) mean=0 std dev = sqrt(0.1) randomdraws = [NV001.get_random_element() for _ in range(1000)] --
