这是一个完整的无线通信系统中物理层的仿真程序，通过扩频技术（直接序列扩频）让信号通过高斯，瑞利等信道进行信噪比分析，得出结论(This is a complete wireless communication systems in the physical layer of the simulation program, through the spread-spectrum techniques (Direct Sequence Spread Spectrum) to signal through the Gaussian, Rayleigh channel for signal to noise ratio, such as analysis, come to the conclusion)

关于直流电机的空载特性的matlab仿真，采用的是样条插值算法对曲线进行拟合，初学者可以改为其他拟合方式看结果如何(With regard to the no-load characteristics of DC motor matlab simulation, using the spline interpolation algorithm, beginners can be fitted into other ways to see the results)

用MATLAB计算大摆角单摆的实验报告，希望对大家有帮助。(simple pendulum)

Goal of the project was to implement numerical methods for solving systems of linear algebraic equations using MATLAB software. First of all I had to learn the structures of programming in MATLAB, later on I was able to implement and test numerical algorithms for solving given problems. All results, comments and conclusion are placed in this report. At the end of the report one can find my MATLAB programs, and sources which were used as a help for me during evaluation. Each task is presented under separated heading, with its full description, problem discussion, my approach for solving it and explanation.

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.

对心率变异性（HRV）曲线进行时域分析时候，主要参数SDNN，SDANN，SDNN_INEDX等的matlab计算程序。(On heart rate variability (HRV) curve when the time-domain analysis, the main parameters SDNN, SDANN, SDNN_INEDX etc. matlab calculation program.)

本程序是针对sar的原始数据到成像后幅度图像的成像过程。。(This is a program about sar image)

说明：  这个是多带谱语音检测，多带谱不仅具有谱熵的有点，还具有能量分析的有点，所以检测的效果很好！(This is a multi-band spectra of voice activity detection, multi-spectral bands not only has a bit of entropy, also has a bit of energy analysis, so the effect of a very good test!)

人工免疫算法的工具箱，有需要就拿去用吧！希望能采纳，(Artificial immune algorithm toolbox, there is a need to take with you! Hoping to adopt)

说明：  利用贝叶斯方法求解标准直线阵列doa估计问题(Using Bayesian method to solve DOA estimation problem)
