WebApr 17, 2024 · Personally, I use Reduce (i am biased since I worked on it), but SymEngine has better performance. 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. http://josephcslater.github.io/sympy-solve-equation-set.html
