[sage-support] efficient determinant of matrix over polynomial ring

2008-09-05 Thread phil
I have a matrix that is composed of multivariant polynomial entries. I want to compute its determinant. The problem is that it is very slow or runs out of memory. For example, R. = QQ[] C = random_matrix(R,10,10) Cdet = C.determinant() # this line takes a long time If you have more variabl

Hi, There is a wiki page for notebook suggestions, but I don't think its been used much lately: http://wiki.sagemath.org/Notebook_suggestions Your suggestion (1) is good, that would be nice. Probably wouldn't be too hard to do. (2) I think is problematic - the way I often use the notebook, I wo

John, apologies for the late reply. Thanks for giving the road map of how to tackle that thing in SAGE. I am very sure if I can do that since I am real newbie to SAGE, but I will give it a try when I have the time. Maybe during the weekend. Thank you very much. Best wishes, J. On 03.09.2008
