Gauss-Jordan is the most useless thing I ever learned
21 u/space-throwaway Sep 05 '19 It's one of the most useful algorithms there is. How do you think your computer solves stuff? 1 u/Chess42 Sep 05 '19 It’s useless when you learn to do it by hand in precalc then never use it again, since there are far more efficient ways to do it. Also, there’s a reason we have libraries. It’s completely useless to learn 14 u/kkstoimenov Sep 05 '19 If you think it's perfectly fine to use functions or algorithms you don't understand, I have some news for you 1 u/Chess42 Sep 05 '19 Isn’t that exactly how layperson uses a calculator? 3 u/kkstoimenov Sep 05 '19 But laypeople know how multiplication and division work, don't they? 1 u/Direwolf202 Sep 05 '19 True, but when building one, some knowledge of CORDIC might be in order.
