I know that there is the command v = M.solve_left(r) to a vector $v$ satisfying the equation. But how can I force it to be a vector over $\mathbb{Z}$? 2022-05-22 10:48:45 +0200 received badge ● Scholar (source) 2022-05-22 10:48:35 +0200 commented answer Solve equation of matrices over integers Hi, Thanks a lot for this.
