I was trying to find the eigenvalues of a matrix. I tried the example from the tutorial (http://www.sagemath.org/doc/ tutorial/tour_linalg.html):
sage: A = matrix([[0, 4], [-1, 0]]) sage: A.eigenvalues () And I got this error: "AttributeError: 'sage.matrix.matrix_integer_dense.Matrix_integer_de' object has no attribute 'eigenvalues'" Can someone please explain this to me? I'm using Ubuntu 9.04, sage version 3.0.5 which I installed from the synaptic package manager.
