Sympy reduce
WebApr 21, 2015 · There are a couple of mistakes with this, but I still find the process elegant: 1. if j == len (A [0]) - 1 should break out of the external while 2. you should check whether A [i] [j] is not zero (and ideally not one), before normalizing 3. you should only multiply other rows if A [i] [j] is not zero. – santamanno.

I don’t do any massively complicated symbolic calculation and prefer work with Julia expressions, so Reduce is good enough for me. If Reduce isn’t good enough, try SymEngine. Also, it seems that Reduce is more portable than SymEngine.
