指派问题的匈牙利解法，从文件中读入待指派的数据。-Assignment problem of the Hungarian method, read from a file to be assigned to data.

用动态规划解矩阵连乘问题-use dynamic programming solution matrix continually multiply problems

#include < stdlib.h > #include < stdio.h > #include < sys/types.h > #include < sys/stat.h > #include < fcntl.h > int 主要 (int argc、 char *argv[]) { int fd、 fd2、 fd3 ； int i; 浅黄色 char [10] ； fd=open(argv[1],O_RDONLY) ； if(fd2=open(argv[2],O_WRONLY) = =-1) { fd3 = 共创 (argv [2]，S_IRUSR |S_IWUSR） ； read(fd,buff,10) ； write(fd3,buff,10) ； } 其他 { fd2=open(argv[2],O_TRUNC) ； read(fd,buff,10) ； write(fd2,buff,10) ； } 返回 0 ； }

绝对精彩，适合初学者-absolutely wonderful, for beginners

并行计算两个矩阵相乘。这个算法是原创的。可以很快实现大型矩阵的相乘。-this is a MPI program that can accompish qucik computation of multiply of two large matrix by parall computation

用C解方程的第2种算法-C solution of the equation algorithms No. 2

k-means 算法接受输入量 k ；然后将n个数据对象划分为 k个聚类以便使得所获得的聚类满足：同一聚类中的对象相似度较高；而不同聚类中的对象相似度较小。聚类相似度是利用各聚类中对象的均值所获得一个“中心对象”（引力中心）来进行计算的。 Matlab 源代码，以兰花数据集作为测试对象。-k-means algorithm to accept input k then n data object is divided into k-clustering in order to make available to the cluster to meet: the same objects in clustering high similarity and objects in different clustering the similarity smaller. Cluster similarity is the use of the clustering of objects by means of a
