21位水仙花数的寻找，里面用到了大数乘法等细节上的东西。(find the 21 digits narcissus.)

计算机常用数值算法与程序(C++版) (Commonly used numerical algorithm of computer and program )

本算法是求取点到曲线的距离，希望对大家有帮助(the algorithm is to strike a point of the distance curve, and I hope to be helpful)

湍流模型re计算流体力学软件udf 可以用于修改UDF文件(turbulence model FLUENT)

多物理场耦合软件采用有限元方法模拟rtfindgen(Coupled multi-physics simulation software using the finite element method rtfindgen)

This directory contains code implementing the K-means algorithm. Source code may be found in KMEANS.CPP. Sample data isfound in KM2.DAT. The KMEANS program accepts input consisting of vectors and calculates the given number of cluster centers using the K-means algorithm. Output is directed to the screen. Usage for KMEANS is: KMEANS SOURCEFILE <enter> The format of the source file is: NPat - Number of patterns (int) SizeVect - Size of vector (int) NClust - Number of cluster centers(int) vect[1,1] ... vect[1,SizeVect] - vector 1 (real) vect[2,1] ... vect[2,SizeVect] - vector 2 (real) . . . . . . vect[NPat,1] ... vect[NClust,SizeVector] - vector N (real) To compile: ICC KMEANS.CPP <enter> (This directory contains code implementing the K-means algorithm.

这些代码可以用于产生一系列随机数，可以根据需要使用。(These codes can be used to generate a series of random numbers may be used as needed.)

求解一维热传导方程，格式包括FTCS、BTCS、CNCS三种差分格式(solve one dimension heat transfer equation. )

说明：  用C语言编写多元线性回归方程，写得不好的地方请指教！(Using C language multiple linear regression equation, where poorly written, please advice!)

稀疏脉冲反褶积代码,包括高尔消元法解矩阵方程阻,自相关,互相关,褶积,反褶积的代码. 刚参加工作那会儿,上进心也足,爱动脑,编了很多的程序,唯有这一个是我引以为傲的,花了几个星期写的稀疏脉冲(预测)反褶积的代码,放到了现在,觉得也没必要再私藏下去了,不出五年,我都不知道这段代码是干什么的了. 希望对大家有用,方法太简单,所以效果不是太好,请大家修改,如要转载,请记得注明出处. (vc++)
