[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

[sage-support] maximum recursion depth exceeded in cmp

Hi, I have a recursive algorithm that works well if it doesn't need more than 5637 iterations. In the case of more than 5637 iterations the error message is: RuntimeError: maximum recursion depth exceeded in cmp Is there a way to make SAGE execute it for more than 5637 iterations? --~--~

[sage-support] QR decomposition of a RQDF-matrix

Hello, I need a QR-decomposition of a RQDF-matrix.It is only possible in RDF. Does there exist something similar for RQDF or do I have to write a function by myself. Thanks! --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To

[sage-support] getting digits

Hi, I have a number like 12.345 and I would like to count the digits. There's a function 123.digits(10) which returns a vector whose length counts the digits. But this only works for integers and I need it for real numbers. --~--~-~--~~~---~--~~ To post to this grou

[sage-support] if-statement with "infinity" or "NaN"

Hi, I want to check if a number is set to infinity or NaN. So I tried this if-statement: if x!=infinity: print x But this doesn't work when x=a/b with a very small b, so that x becomes infinity. (I'm using SAGE Version 3.0.1) Agi --~--~-~--~~~---~-
