RE: Acron RPN announces v3.0 BETA
Anyone found any problems or functionality gaps with v3? I'm looking for something new to entertain myself over Christmas vacation.
I've been playing with replacing my Rombergbased integral algorithm with a NewtonCotes quadrature. I'm getting results at least as good as my old algorithm, plus some tweaks I've made seem to be working quite well for improper integral ranges such as (a, b], (a, b), [a, ∞), (∞, ∞), etc. I tried supporting complex a, b too, but that was painfully slow and I eventually dropped it. I'm going to try supporting ∫∫ ƒ(x,y) dxdy next. So long as I'm only changing math logic instead of UI, there's no real lag in porting to iOS, so I could probably get something out in early Q1.
