2017-11-10 21:43:35 +0100 | asked a question | Home and End Key Hi all, I am using Sage on my mac terminal. The mac keyboard does not have home or end key. I check out several combinations and they does not work in Sage terminal platform, but works on Rstudio. How do I recover the home and end key? Thanks. |

2017-09-21 20:19:26 +0100 | asked a question | Stochastic block model Hi all, I would like to draw a random graph by Sage. The general stochastic model is the following: The graph contains $n$ vertices and the n vertices are divided into $r$ communities $C_1\cdots,C_r$. For two vertices within the same community, there is a probability $P_r$ that they are connected directly by an edge. How do I plot such a graph in Sage? References appreciated. |

2016-02-10 02:21:24 +0100 | asked a question | Define different embedding of a number field Hi, Let f(x) be an irreducible polynomial over $ZZ[x]$. We can define a number field My question is how does one define all the embedding of K into the real or complex in Sage? |

2016-02-08 03:36:16 +0100 | asked a question | write output of for loop in pari to file Hi all, I would like to write the output of a for loop in Pari to a file named 'foo', However the output of a for loop has no numbering contrast with other output. If I look at the numbers labeling the outputs before and after the for loop and use that number in the following command \w n foo Then what I get in foo is 0. What happened and how can this be fixed? |

2016-02-08 00:04:39 +0100 | asked a question | Number field arithmetic in Pari/gp Hi all, I would like to do number field arithmetic in Pari. To be more precise, I would like let Pari do the following job as Sage does, where f(x), g(x) are irreducible polynomials over the rational. I would like to do arithmetic with a,b. This is easily done in Sage. How can I do this by Pari? Thanks |

2016-02-06 20:47:22 +0100 | asked a question | Define a big matrix in Sage Hi all, I would like to define a big matrix E (130$\times$ 30) with entries being a list like E[11,1] = [x, [1,-2]]; E[14,1] = [x, [1,-1,-2,1]]; or 0. These entries are stored in a separate file which is readable by Pari but not Sage. How do I define it by Sage? |

2016-02-06 18:32:09 +0100 | commented question | cannot exit pari This happens for Sage installed on my laptop and also that installed on my university's server. I type |

2016-02-05 22:34:25 +0100 | asked a question | save gp object to sage readable sobj Hi all, I am doing computation with a Pari readable table. Since I am a beginner to Pari, I would like to know that after defining a number field for example $K=nfinit(x^2-76)$, how do I play around with the generator $x$? This is super easy in Sage and may be silly question for people familiar with Pari. It also solve my problem if you know how to save a big matrix defined in Pari to an object readable by Sage. |

2016-02-05 22:20:23 +0100 | commented question | How to load gp file in Sage terminal and list all its content Dear vdelecroix, I am doing computation with Stein's tables at [http://wstein.org/Tables/an.html], William Stein says it is readable by Pari. However when I failed to load it by the Pari kernel installed in Sage. But it is OK now once I installed Pari on my laptop and load the database there. The bug may be due to the fact that Pari is not embedded in Sage perfectly. |

2016-02-04 19:06:01 +0100 | asked a question | cannot exit pari Hi all, I meet the following problem when exiting pari: It reports that I clicked control+C for a couple times, it can exit but no if I do nothing. Is this a bug? Sage is installed on a ubuntu system. |
