牛顿迭代，雅克比,求解非线性方程组 数值分析 MATLAB相结合(Jacobi NEWTON)

设T 是一棵带权树，树的每一条边带一个正权。又设S 是T 的顶点集,T/S 是从树T 中 将S中顶点删去后得到的森林。如果T/S中所有树的从根到叶的路长都不超过d ，则称T/S 是一个d 森林。(this is a project )

SPH 源代码，用于科研计算，是光滑粒子流体动力学-一种无网格粒子法书后的源代码(SPH source code, for scientific computing, is a smoothed particle hydrodynamics -- a source code after a meshless particle method.)

Levenberg Marquardt算法的matlab代码,简洁无误,结构清晰,便于快速学习。( LevenbergMarquardt algorithm matlab code, simple and correct, clear structure, easy to learn quickly.)

说明：  牛顿迭代法的matlab代码，数值分析中重要的一个算法(Matlab code of Newton iterative method)

说明：  Do you need to gain confidence with handling numbers and formulae? Do you want a clear, step-by-step guide to the key concepts and principles of statistics? Nearly all aspects of our lives can be subject to statistical analysis. Statistics: An Introduction shows you how to interpret, analyze and present figures. Assuming minimal knowledge of maths and using examples from a wide variety of everyday contexts, this book makes often complex concepts and techniques easy to get to grips with. This new edition has been fully updated. Whether you want to understand the statistics that you are bombarded with every day or are a student or professional coming to statistics from a wide range of disciplines, Statistics: An Introduction covers it all.

NSGA2 and MOPSO algorithms

这里实现了一个最优化控制的算法，牛顿梯度法的源代码，运行于matlab平台下。(here to achieve optimization of a control algorithm, Newton gradient of the source code, which runs on Matlab platforms.)

本算法是基于数值计算中的SQP编写的MATLAB程序。非常实用的一个小程序。(This algorithm is based on the numerical calculation of SQP written MATLAB program. Very practical one small program.)
