Hi, I have the following matrix and want to determine the eigenvalues of it.
M3=matrix(RR,[ [0, 0.095, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0.905], [0.255, 0, 0.745, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0.255, 0, 0.745, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0.905, 0, 0.095, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0.255, 0, 0.745, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0.255, 0, 0.745, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0.905, 0, 0.095, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0.255, 0, 0.745, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0.255, 0, 0.745, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0.905, 0, 0.095, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0.255, 0, 0.745], [0.745, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0.255,0]]) M3.eigenvalues() I got the following message: NotImplementedError: eigenvalues() is not implemented for matrices with eigenvalues that are not in the fraction field of the base ring or in QQbar I have no idea what the message mean as I don't have enough math backgrounds to make sense of it. I tried to do the same thing on Mathematica and I got several complex eigenvalues. I wonder if sage does not support determining complex eigenvalues. -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
