2015-12-31 00:24:48 +0100 | asked a question | line numbers in web notebook I use Sage in my Mozilla Firefox browser as notebook and wanted to know how i get line numbers in my computing cells. |

2015-12-31 00:19:24 +0100 | commented question | Declare variable as function output It is ok :) I just forgot to use return ;) |

2015-12-31 00:18:36 +0100 | commented answer | Declare variable as function output Thanks :) That was exactly the problem. I only used print instead of return :) |

2015-12-28 15:32:16 +0100 | asked a question | Declare variable as function output hello guys, i wrote a new function, lets call it "func", that has some matrix as input and also some matrix as output. the thing is, i want to declare the last output of the function as a new variable x ( x=func(A) for a given A) the problem is: if i say i get : I guess the problem is, that i calculate more than one thing while the function is running, but at the end i just want to able to use that one single output of the function for further use... |

2015-12-23 14:27:45 +0100 | asked a question | Naming variables in a loop I have this problem: Lets say i have an matrix A and use A.gram_schmidt() on it. then i get a matrix B whose rows are orthogonal. So what do i do now if i want use the vectors of the rows. How can i make them to variables practical? I tried this: But clearly this doesnt work, because sage doesnt identiy the "i" in "wi"... |

2015-12-23 12:06:03 +0100 | commented question | Function with Matrix input Oops... that was quite some fail... Sorry :) |

2015-12-23 10:55:33 +0100 | asked a question | Function with Matrix input Hello Guys i have the following problem. I want to write a function whose input is a Matrix. A small example: but then i get : How can I write i function that has an Matrix as input? |

2015-11-28 22:38:24 +0100 | commented answer | Saving my sage session into a .txt file from Interactive Shell IOError: [Errno 2] No such file or directory: '/home/nbruin/hist.txt' I thank you a lot buddy. But i dont want to cause you any more trouble... Forget it |

2015-11-28 22:06:39 +0100 | commented answer | Saving my sage session into a .txt file from Interactive Shell well the information is right except that my files arent saved there anyway. and your tipp with notebook isnt working either. "cp" is not defined... I have no clue what sftop-ing is... and I somehow feel like i am a little bit too much of an computer noob to get it right... |

2015-11-28 20:52:52 +0100 | commented answer | Saving my sage session into a .txt file from Interactive Shell Well thanks a lot... I got out, that the path is but unfortunately i have no clue how i get there... Sorry buddy, that i am still not able to do it after all your efforts :/ |

2015-11-28 11:15:42 +0100 | commented answer | Saving my sage session into a .txt file from Interactive Shell Hmm i used the history command.... but now i dont find the file -_- I even searched for it with the windows-function... but nothign is found... God... that Virtual Machine for Windows is frustrating... Do you have Linux or Windows yourself? |

2015-11-27 22:02:48 +0100 | asked a question | Saving my sage session into a .txt file from Interactive Shell Hello guys, I have the following question: Lets say i run a sage session and at the end i got this written in my Interactive Shell after the session And now i want to save all of the above into a txt-file. Is that possible and when yes how? |

2015-11-22 20:02:21 +0100 | asked a question | Multiple outputs with Sage Notebook Hello Guys, i have the following question. I use Sage on Windows so I use the Sage Notebook in my browser. I wanted to know if there is a possibility to get more than one output from that without going to a new "compute cell" for everything i want to be computed... For example: When i have i only get output from the last command (as result 1) But i want to get output from every line i marked above with +++. Is there annother possiblilty than using a new compute cell after every line i want to have output from? |

2015-11-22 19:52:47 +0100 | marked best answer | Calculate Inverses Hello Guys, i have the following problem. I got the Ring $ R = \mathbb{Z} /(x^7 -1)$ and the polynom f(x) = $x^6 - x^4 +x^3 + x^2 -1 \in R$ and want to compute the inverse of f(x), $f(x)^{-1}$. How do I do that? |

2015-11-22 19:52:46 +0100 | commented answer | Calculate Inverses Thanks once more. |

2015-11-22 15:43:32 +0100 | commented answer | Calculate Inverses Thanks a lot. Sorry to bother you more, but... when i use $ R = (\mathbb{Z} /7 \mathbb{Z}) /(x^7 -1)$ instead, does it work the same? And in you line 3 you say: "f = RR(x^6-x^4+x^3+x^2-1)"... i dont know exactely what this is good for (like i said... i am totally new to sage). Does that mean you are are looking at x^6-x^4+x^3+x^2-1 as an element in RR? |
