Currently I am using right nullity and the solve_right function separately, which I think results in some redundancy. Any advice on what I should do? There doesn't seem to be an obvious solution from the manual.Thu, 22 Mar 2018 15:29:22 -0500https://ask.sagemath.org/question/41719/avoiding-redundancy-in-checking-uniqueness-of-solution-to-linear-equation/
