I need to compute elementary divisors of a matrix (xI-A), where A is a matrix defined over GF(2). So, i try to define a univariate polynomial ring (R) over GF(2) and compute the elementary divisors of (xI-A) using the elementary_divisors() procedure. But as the size of the matrix increases, the algorithm is too slow. My matrices are of dimension 100.
Can anyone suggest an alternative approach to solve the problem. Sun, 03 Jun 2018 18:56:18 +0200https://ask.sagemath.org/question/42485/elementary-divisors-of-a-matrix/
