[sage-devel] error while building the documentation: where?

Hello, I am working on my favorite branch and try to build the documentation. It fails with the error below with no information about which file causes it! How can I find which file triggers the error? Traceback (most recent call last): File "/opt/sage/src/doc/common/builder.py", line 83, in f

No, I have no idea of what will be the degree of the number field in which my spectral radius belongs to. But if I could compute the characteristic polynomial of the matrix, I could have the minimal polynomial of the spectral radius (and that's what I mean by exact value). Le jeudi 27 mars 2014

Do you have an idea of the expecting degree of the number field in which your eigenvalue belongs to ? If yes you can use pari/GP otherwise I do not see what you mean by exact value. 2014-03-27 11:17 UTC+01:00, Paul Mercat : > OK, thank you, I see. > It's an efficient method to compute a approximat

2014-03-27 Thread Paul Mercat
OK, thank you, I see. It's an efficient method to compute a approximation of the spectral radius. It's good but I still want to have the exact value. Maybe I can find the exact value from the approximation ? Le mercredi 26 mars 2014 23:56:49 UTC+1, vdelecroix a écrit : > > You compute powers but
