Nins and me got *different* random matrices : his was composed of integers in (-2..2), and Sage could compute its eigenspaces ; mine was :
sage: with seed(0): M = matrix(AA, 3, 3, lambda u,v: AA.random_element()) sage: M.apply_map(lambda u:u.radical_expression()) [ -sqrt(2) - 1 -1/4 -2*sqrt(3)] [ 1/2 1/8*sqrt(33) + 1/8 -1/5*sqrt(29) + 3/5] [ 0 1/4 1/2] which, BTW, shows a problem about the reproducibility of random elements between Sage versions and/or platforms… Could you post *your* random matrix ? And could you try : M.95 = matrix(AA,3,3,[-sqrt(2) - 1, -1/4, -2*sqrt(3), 1/2, 1/8*sqrt(33) + 1/8, -1/5*sqrt(29) + 3/5, 0, 1/4, 1/2]) ES = M95.eigenspaces_left() and report if you get a result ?
