PCA人脸识别源代码

利用NEWTON的原理进行适当的改进，得到的算法-use of the principle for appropriate improvements, the algorithm

为了改进基本人工鱼群算法的寻优效果，提出加入生命周期和生命指数的方法，在此用matlab语言实现，实验结果较优

void CRSLAIDoc::CString2Char(CString TempCString,char ch[]) { int i; char *tmpch; int wLen=WideCharToMultiByte(CP_OEMCP,0,TempCString,-1,NULL,0,NULL,NULL); tmpch=new char[wLen+1]; WideCharToMultiByte(CP_OEMCP,0,TempCString,-1,tmpch,wLen,NULL,NULL); for(i=0;tmpch[i]!="

固定边界条件下的三次样条插值matlab程序-fixed boundary condition；cubic spline

这个是机器学习实战的部分代码，亲测可用。。。比较适合于入门学习。。。。很不错的。。。现在只是上传了源码的一部分，之后的以后会陆续上传上来。。。希望大家一同学习进步。。。。。。

级数展开法计算圆周率精确到千万位以上-Series calculated pi accurate to more than 10 million

k均值聚类方法的c代码，并且带有聚类数据，适用于刚刚接触该算法的初学者-k-means clustering method c code, and with the clustering data, applicable to just access to the algorithms for beginners

featflow1.3RC10，有限元-流体，老外开发的，不错。-featflow1.3RC10, finite element- fluid, foreign development, yes.

利用AFEPack包求解变二次系数的椭圆型方程.在求解这个问题的过程中，先要把程序的结构进行整理，将变二次项系数的因素加进去 ，并使得其更加有利于复杂一些的问题的求解 。为此，我们使用一个类来管理这个求解的问 题，先写一个对这个类进行声明的头文件 EllipticEquation.h-Use AFEPack package for solving variable coefficient elliptic quadratic equation. In solving this problem, the first to organize the structure of the procedure will change coefficient of quadratic terms added to the list of factors, and make it more conducive to the complexity of some of the problem solving. To this end, we use a class to manage to solve this problem, first write a statement of this type for the header files EllipticEquation.h
