说明：  在matlab中实现巴特沃斯低通滤波器as=70 Fs=15000 Fp=9000 (butterworth lowpass filter as=70 Fs=15000 Fp=9000 )

双稳态随机共振的参数寻优算法，先固定b，寻求a，画出随a的信噪比增益变化曲线(Parameter stochastic resonance algorithm)

利用basis pursuit算法计算图形重建，利用compressive sensing技术使用较少的数据进行图形恢复(Use basis pursuit graphic reconstruction algorithm using compressive sensing technology uses less data graphically recovery)

ISOMAP算法，其中做了部分修改。算法采用K近邻图计算测地距离的方法，最后进行低维嵌入(ISOMAP algorithm, which made some modification.Algorithm of geodesic distance is obtained by using the K neighbor graph method, finally to low dimensional embedding)

说明：  MATLAB在电子信息工程中的应用[张德丰][程序源代码](MATLAB in Electronic Information Engineering [Zhang Defeng] [source code])

最小二乘支持向量回归模型 直接输入训练集和测试样本即可(Least squares support vector regression model direct input training set and test samples )

随机森林指的是利用多棵树对样本进行训练并预测的一种分类器，包括两个方面：数据的随机性选取，以及待选特征的随机选取。(Random forest refers to the use of more than one tree to sample the training and prediction of a classifier, including two aspects: random selection of data, as well as the characteristics of random selection.)

说明：  可以实现图片中的数字识别，并将识别之后的数字写入文本文件中，数字可以式多行，可以长度不同才可以(But realize the number recognition in the picture, and write the recognized number into the text file.)

Used to obtain the particular position where a maximum or minimum occurs in a matrix

用matlab仿真的空时分组码2根发射天线一根接收天线(Matlab simulation using space-time block codes two antennas a receiving antenna)
