Hi Edgar, Thanks for the report. We need to get eigenvalues for symbolic matrices from Maxima (I think), but we could certainly get eigenvectors naively via matrix kernels as you suggest.
I did a simple experiment and only computed the appropriate kernel for a symbolic matrix and one of its symbolic eigenvalues in hopes that this would not spawn a Maxima session in a fresh Sage instance. No luck. So some more testing may be necessary to see if this approach is faster, or can be arranged independently of Maxima (if desired). In any event, I've made a ticket with a link back here, and put it on my list - though I won't get to it immediately, so it is fair game for anybody else who may be interested. http://trac.sagemath.org/sage_trac/ticket/11145 Rob On Apr 4, 2:31 pm, Edgar Duenez-Guzman <eadue...@gmail.com> wrote: > I have been struggling with symbolic computation of eigenvectors > and eigenvalues of 4x4 matrices.
