用于iOS上的非线性拟合的lib [英] lib for Nonlinear Fitting on iOS

问题描述

我需要在iOS应用程序中拟合一些数据，基本上要遵循牛顿的冷却定律:

I need to fit some data in an iOS app, basically with Newton's Law of Cooling:

y = a + b * c^{x}

我找到了 GNU科学图书馆可能会解决此问题，但是出于GPL的考虑，这是没有考虑的.是否有任何具有商业友好许可(例如BSD，APL等)的C/C ++开放源代码非线性卡方求解器?

I found the GNU Scientific Library is likely to handle this, however, it is out of consideration for the sake of GPL. Is there any open-sourced nonlinear Chi-Square solver in C/C++ with a commercial friendly license (e.g., BSD, APL etc.)?

期待您的建议.

推荐答案

似乎MINPACK可以胜任这项工作.

It seems that MINPACK could do the job.
