相似度算法的实现， 在利用支持向量机进行模式分类的时候，有时需要考虑到实时性，为了提高实时性，则利用相似度算法减少样本集个数，从而减少训练时间和支持向量的个数，使得建立起的向量机实时性提高。(Similarity algorithm, support vector machine in pattern classification, it is sometimes need to take into account the real-time, in order to improve real-time, the use of similarity algorithm to reduce the number of sample collection, thus reducing training time and the number of support vectors， improve the real-time of established Vector Machines.)

利用MATLAB程序编写的语音识别系统界面，很经典(Using MATLAB programming speech recognition system interface, very classic)

Compared with other forms of motor, permanent magnet synchronous motor (PMSM) has better dynamic performance, smaller size and higher efficiency

将采用训练函数 traingdx 和“提前停止”相结合的方法来训练 BP 网络，以提高 BP 网络的推广能力(Will use the training function traingdx and " stop ahead" a combination of methods to train BP network to improve the generalization ability of BP network)

添加wav文件或者录音 实现频谱分析 是个MATLAB文件(Add wav files or recording to achieve spectral analysis)

该代码为PCA主成分分析，可用于特征选择，选取贡献最大的前三个主成分(The code for the PCA principal component analysis, can be used for feature selection, select the largest contribution to the first three principal components)

用于生成低通滤波器传递函数，有调用函数，两个一起才可以用。(Used to generate low-pass filter transfer function. Have to call a function with only two can be used.)

说明：   matlab实现手势模式识别的作业，实现算法为模式识别课程中介绍的简单算法(matlab gesture recognition to achieve the operating)

in this project data is hiding by LSB stegnography the shifting opertor is used to shift the data

本代码用simulink实现IIR滤波的仿真(The code used to achieve IIR filter simulink simulation)
