[sage-support] Dirichlet L-function

Is there a way to compute Dirichlet L-functions http://en.wikipedia.org/wiki/Dirichlet_L-function ? I tried lcalc.twist_values() but it doesn't work. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this gr

After you type lcalc.twist_values? and look at the examples given, can you tell which command does not work, what operating machine you are using and version of sage you are running? On Sat, Apr 25, 2009 at 9:20 AM, agi wrote: > > Is there a way to compute Dirichlet L-functions > http://en.wiki

2009-04-25 Thread dpvc
Thanks for posting the new example. I have found that the problem is due to the fact that Sage puts the output inside a block, and IE7 gets confused about some of its measurements in that case. It can be fixed by including span.typeset { white-space: normal; } in the css/main.css fil

[sage-support] DSage on Amazon EC2

Hi, I just wonder - does anyone have experience on running DSage on Amazon EC2 (on preferably more than one instance) or similar Cloud-Computing service? I'm preparing to try out the platform but because of it's non- zero cost I'd prefer not go in blind, would be very happy if someone who did it

I have made a patch that attempts to limit the number of snapshots that get saved (per worksheet) to an absolute maximum of 30. There's a bit of a dilemma about just how to do this, given that at present some users will have more than 30 snapshots for some worksheets, and in the future this limit
