开源 Objective-C 数学/计算器引擎
大家好，
我想知道你们是否知道任何用 Objective-C 编写的运行良好的数学或计算引擎？已经找到了一个使用 CorePlot 的绘图...... 感谢您的帮助！ :)
Hej guys,
I was wondering if you know any well working Math or Calculation engines written in Objective-C? Found a graphing one using CorePlot already....
Thanks for your help! :)

您可能会从 David Stes 的 CAKit（计算机代数包）中得到一些用处，但是您将需要做大量的黑客工作，因为 Stes 强烈反对 FoundationKit，并根据旧的 NeXT 之前的版本编写了整个内容ICPak API。 （不要向他寻求帮助——你会受到很大的伤害。）
要记住的关键问题是 ICPak 基于 Smalltalk 并或多或少地描述了该类的预期功能，而 FoundationKit类名倾向于描述原始功能本身；最有用的相关性可能是 OrdCltn ->; NSMutableArray；您还必须调整内存管理以使用自动释放。这并非不可能，但你必须了解 FoundationKit 所遵循的哲学。
You might get some use out of David Stes' CAKit (a computer algebra package), but you'll have a ton of hacking to do, since Stes is ravingly anti-FoundationKit and wrote the whole thing based on the old, pre-NeXT ICPak API. (Don't go looking to him for help -- you'll get a world of hurt.)
The key issue to keep in mind is that ICPak was based on Smalltalk and describes more or less the intended function of the class, while FoundationKit class names tend to describe the raw functionality itself; the most useful correlation will probably be OrdCltn -> NSMutableArray; you'll also have to tweak the memory management to use autorelease. It's not impossible, but you do have to understand the philosophy that FoundationKit follows.
