2014-02-04 13:17:52 -0500 | asked a question | Ubuntu PPA not updating I'm using Ubuntu and have previously had my sage automatically update to the latest version. It's now stalled at 5.13 and didn't upgrade to 6.0 or 6.1. I followed the instructions on http://sagemath.org/download-linux.html which says to give these commands. This used to work but has stopped. Any ideas? |

2012-06-07 04:39:00 -0500 | asked a question | Tkinter for sage 5.0 on linux I'm using sage 5.0 on Ubuntu Linux. I would like to use Tkinter but it fails. I have Tk installed (works from ordinary python) and the development libraries are installed. Here's what happens: I tried the instructions here: http://wiki.sagemath.org/faq?highligh... but that didn't work. I tried a more simple and got this: Help please! BTW: The from Tkinter import * works perfectly on my Mac. Thanks!! |

I would like to generate a random integer according to the binomial distribution. That is, I would like to generate a Bin(n,p) random value. That's number between 0 and n in which the probability we get the value k is Here is an inefficient method (which requires n calls to Is there a better way to do this (already built into Sage, I hope)?

2011-11-20 12:05:20 -0500 | asked a question | Creating a semilogx (or semilogy or loglog) plot I would like to create a semilogx plot of some data. I have two lists of data and would like to use something like list_plot() to visualize the data, but the x-axis should be logarithmic. I have attempted (and failed) in using pyplot, but get an error message like this: which I don't understand. Is there an option to plot() and/or list_plot() that allows one to choose logarithmic axes? Thanks. |
