利用matlab进行动力学仿真之二，学习理论力学的同学可以参考一下(Dynamics simulation carried out using matlab bis, learning theory mechanics students can refer to)

模拟产生（7，4）汉明码及其监督矩阵，并用产生的监督矩阵判断传输的码字是否有错，如果有错，指示出其出面错误的位置 (Simulated (7,4) Hamming code and its monitoring matrix, and supervision of the resulting matrix to judge transmission codeword is wrong, if wrong, indicating that it came forward to the wrong location)

一本学习matlab7.0的好书，不过是英文版，需要耐心看。(a study matlab7.0 books, but in English, requires patience to see.)

如何减少ISI？分别用NLMS,BLMS，基于符号的LMS算法完成仿真，并比较结果，包括不同信道参数w，不同数据块长度L对其的影响。(How to reduce the ISI? Respectively NLMS, BLMS, symbol-based LMS algorithm to complete the simulation, and compare the results, including different channel parameters w, different data block length L of its impact.)

64 QAM mod and demod

说明：  假设每个延时单元延时10ms.被传输的基带信号x(t)是一个0，1交替变换的矩形二进制脉冲序列，脉宽为10ms，并假设x(t)通过一个稳定的散射信道后才到达均衡器，成为2径信号，这两路信号幅度相等 ，相隔15ms。用MATLAB实现一个2级LMS均衡器(equalizer)

《MATLAB神经网络30个案例分析》中的第12个例子，案例12 SVM神经网络的数据分类预测-葡萄酒种类识别。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 12 cases 12 data classification of SVM neural network prediction- wine species identification. Hope to have certain help to everybody! )

说明：  ABS整车控制模型，系统全面，配有文字说明，清晰易懂(ABS vehicle control model, comprehensive system)
