Dear linear algebra specialists, I am stuck with an elementary linear algebra problem where Sage is (for now) of no help. I want to compute the rank of a 30 x 30 dense matrix over a number field of degree 30.
sage: x = polygen(QQ, 'x') sage: K = NumberField(x^30 - 3, 'a') sage: M = MatrixSpace(K, 30) sage: m = M.random_element() sage: m.rank() See also https://ask.sagemath.org/question/50626/compute-dimension-of-vector-subspace/ Any hint?
