Hi,
I need to do an RQ decomposition (though QR would be a start) for a matrix with entries in Laurent series ring over a finite field. A matrix over ZZ and other special rings could be sent to SciPy to do the decomposition, but Laurent series aren't quite so amenable. If anyone has some good ideas to do this, I would appreciate it. Most of the algorithms I have seen take the norm of a vector to normalize the rows of Q. There's not a square root in the Laurent series ring, so one might need to just use the sum of squares of the entries of the vector. The rows of Q won't be normalized in that case, but that's fine for what I need. -Salman --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
