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.

该matlab程序实现字母T和L的区分，在9*9格形框里，字母T和L有不同的位置，任意位置，神经网络都可以识别出是T还是L(The program matlab and distinguish letters L, T, in the grid-shaped box 9* 9, the letters L and T have different locations anywhere in the neural network can identify a T or L)

ldpc码的编解码实现，实现了图像的加水印，去噪，加噪声等功能，IMC-PID是利用内模控制原理来对PID参数进行计算。( Codec ldpc code implementation Realize image watermarking, de-noising, plus noise and other functions, The IMC- PID is using the internal model control principle for PID parameters is calculated.)

检测概率PD与输入信噪比r的关系（理论曲线） 采样点数：N=100；噪声方差：sigma^2=1 ( Probability of detection PD relationship with the input signal to noise ratio of r (theoretical curves) sampling points: N = 100 noise variance: sigma ^ 2 = 1 )

说明：  matalb的原代码主要用圆管的分析，应该有实用价值。(Dimensional analysis and scaling ：Dimensional analysis is a tool based on the observations )

说明：  这是作者自己编写的基于matlab语言的程序设计。遗传算法的函数优化 应用。 (is prepared by the author himself on the Matlab programming language. Genetic Algorithms Optimization applications.)
