2018-09-12 02:18:14 +0200 | asked a question | Sage does not see Imagemagick I am trying out the animation thing in http://doc.sagemath.org/html/en/refer.... But Sage keep saying And indeed returns false. But I do have ImageMagick installed by homwbrew. i.e. it works perfectly in Terminal. What Could Possibly Go Wrong? (macOS 10.13; Sage 8.3; Imagemagick 7.0.8.) |

2018-02-07 01:14:04 +0200 | commented question | It takes so long to generate dictionary of GL elements. @slelievre before 8.0 now 8.1 and everything is good now. @dan_fulea: I am implementing a group action that is quite tedious.

2018-02-07 01:05:00 +0200 | commented answer | It takes so long to generate dictionary of GL elements. Thank you. I did update from 8.0 to 8.1. I was not aware of the version-issue because I thought I was quite new. Now everything works fine. |

2018-02-06 02:03:25 +0200 | asked a question | It takes so long to generate dictionary of GL elements. The following command takes 9 seconds to execute. On the other hand takes minutes and does not seem to terminate. If I understand python dictionary correctly, they should take about the same time. So what happened? |

2017-12-20 03:10:14 +0200 | commented question | Making a dictionary of matrices @dan_fulea Well I expect the dictionary to record not only entries but also the width and height. If I come up with a method that turns a matrix into a hashable matrix then I am reinventing |

2017-12-19 23:16:31 +0200 | asked a question | Making a dictionary of matrices I am trying to make a dictionary of matrices. Ideally But Sage refuses to hash (mutable) matrices. I then tried which gives I also tried making a dictionary of tuples which raises no errors; However gives
What is the best, if possible, way to make a dictionary and lookup matrices? |
