Lagrange algorithm with C language

辛普生数值积分，已在TC2.0环境中编译通过-Health numerical integration Simpson has been compiled WITH TC 2.0 environment through

用来求解非线性系统中分岔,混沌,周期,准周期等动力学,可以求数值解,也可画图,只要知道系统模型,可以根据需要自由修改参数,软件带有使用说明,简单易懂-Used to solve nonlinear systems in the bifurcation, chaos, periodic, quasi-periodic dynamics, etc., you can seek numerical solutions, but also drawing, as long as know the system model, you can freely modify the parameters as needed, the software with instructions for use, simple and easy to understand

改代码对于学习数据结构和算法来说是必不可少的书籍，代码中提供了各种类型算法的详细程序

清华大学2002年出版的《科学与工程数值计算算法VB》配套源码，包括复数计算、矩阵运算、插值计算、线性非线性方程组求解、数值积分、数值拟和与逼近等算法和类，对于科学和工程数值计算很有参考价值！-Qinghua University, in 2002 published "Science and engineering numerical algorithm VB" complementary source, includes the plural, matrix computation, interpolation, linear solve nonlinear equations, numerical integration, and the proposed numerical approximation algorithms and other categories, science and engineering numerical computation of great reference value!

李学武提交的C语言源代码，包括Hilbert曲线，高精度计算，π值计算公式，取石子游戏，趣味等式填数游戏3则，验证四色定理等- Li Xuewu submits the C language source code, including the Hilbert curve, the high accuracy computation, pi the value formula, takes the gravel game, the interest equality fills in the number to play 3 pieces, confirms four colors theorems and so on

这个是斯坦福大学在coursera 公开课上的机器学习的练习2的习题答案和原题。仅供参考。 有在学习机器学习的同学，可以选择andew_ng在coursera 公开课上的机器学习，这是一个很好的课程，而且算法讲的很详细，这个代码是里面练习的参考答案之一，对于刚开始学习的同学很有用。

Polynomial fit functions === === RegressionObject.cls contains a class that provides an easy way to add polynomial regression functionality to any application. If you just want linear regression or a very high degree, no matter: this class has good performance and scales seamlessly with the complexity of your problem.-Polynomial fit functions === === === === RegressionObject.cls contains a class that provides an easy way to add polynomial regression functionality to any application.
