heuristic optimization

此程序是matlab中给出矩阵均值的程序，注释详尽，使用简单，其中的注释详细，自己可以对变量做相应的变换(This procedure is given in matlab matrix mean the procedures, the Notes detailed, easy to use, which notes in detail that they can make the corresponding change of variables)

用Matlab编写的天空之城，分享给大家听听(Matlab prepared Laputa, share them to you)

Sistema de Ventas - VF

The NCT includes 4 External validity indices and 8 internal validity indices, and the sub-routine validity_Index.m is designed to use them. This tool is suitable for the research work such as the performance comparison of different indices on estimation of the number of clusters, algorithm design by improving part codes of this toolbox. i) External validity indices when true class labels are known: Rand index Adjusted Rand index Mirkin index Hubert index ii) Internal validity indices when true class labels are unknown: Silhouette Davies-Bouldin Calinski-Harabasz Krzanowski-Lai Hartigan weighted inter- to intra-cluster ratio Homogeneity Separation iii) Others Error rate (compared with true labels) System Evolution: it is used to estimate the number of clusters and give separable degrees between clusters.

说明：  GA优化BP网络，matlab编程设置神经网络三层，并有数据测试验证(GA optimizes BP network, matlab programming sets up three layers of neural network, and has data test verification)

A Plate Element displacements for effective shear force

Matlab源程序用动态规划方法求最短路径。(Matlab source code using dynamic programming method for the shortest path.)

本文介绍了变结构控制的原理，并进行了MATLAB仿真(In this paper, introduced the priciple of system of variable structure control program and a MATLAB simulation)

该程序不使用matlab自带的程序，自主编写，进行简单更改可以实现多中功能，算法思想是滤波器的实现！(The program does not use matlab own procedures, self-writing, more than a simple change in function can be achieved, the algorithm idea is the realization of filters!)
