2008-10-22 Thread salmanhb
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 id
