How can I check if the matrices below are left coprime to each other? How to find the greatest common divisors when the matrices below are not left coprime to each other? How to solve these problems using software like MATLAB, Wolfram Mathematica, etc...? a) (s -s 0 s^2) (0 (s + 2)^2 -(s + 1)^2 (s + 2) (s + 2)). b) (s -s(s + 1)^2 0 -s) ((s + 1)^2 (s + 2)^2 0 0 s(s + 2)). c) ((2s + 1 (s + 1)^2 s^2 + 1 s^2 + 2s) (2s^2 + 3s + 5 s^2 + 5s - 1 s^2 + 4s + 1 s^2 + s - 1)
