是基于主成成分和核主成成分的实例，有详细的注解，条理清晰易懂，适合初学者对pca与kpca的学习。(Is based on the principal as the main components and nuclear components as examples of the comments in detail, the clarity of easy-to-understand for beginners and pca learning kpca.)

说明：  4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)

matlab中对简支梁进行有限元建模，并进行模态分析(matlab for Charpy in finite element modeling and modal analysis)

sigma-delta调制器工具箱，包括SIMULINK和MATLAB(sigma-delta modulator toolbox, including MATLAB and SIMULINK)

Kalman filter very good

主成分分析程序，简单易懂，修改路径可直接运行，附带详细说明(The PCA program with detailed explanations is very useful and effective，easy to understand. It can be run after modifying the input path.)

3维重建的一些例子，基于matlab平台(Some examples of three-dimensional reconstruction, based on matlab platform)

说明：  Cachy分布，产生cachy 分布的概率密度，随机数(Cachy distribution)

zero crossing feature extraction
