G-P算法计算关联维数，可以运用在混沌时间序列的瓦斯浓度预测研究中(GP algorithm to calculate the correlation dimension, you can use the gas concentration in the prediction of chaotic time series in)

用双线性变换法设计IIR数字滤波器 （1）用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为：在通 带内频率低于0.2π 时，最大衰减小于1dB；在阻带内[0.3π ,π ] 频率区间上，最小衰减大于15dB。 （2）以0.02π 为采样间隔，打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性 曲线。 （3）用所设计的滤波器对实际心电图信号采样序列（在本实验后面给出）进行仿真滤 波处理，并分别打印出滤波前后的心电图信号波形图，观察总结滤波作用与效果。 (err)

用Matlab编写的功率谱估计，输入数据是100年太阳黑子活动记录，用周期图法、最大熵值估计（AR法及Burg法），画出信号功率谱进而算出太阳黑子活动周期。(Matlab prepared using power spectrum estimation, input data is 100-year record of sunspot activity, using periodogram method, the estimated value of maximum entropy (AR Law and Burg method), draw the signal power spectrum and then calculate the sunspot activity cycle.)

LMS Classical algorithm

本程序基于“图像模式识别—VC++技术实现”写就，实现了线性和非线性手写数字识别。 程序主文件是homework.m 具体实现可以参考程序内注释。 (this is a matalb programme,in order to recognise the number writtern by yourself. it include homework.m,homework.fig,Getfeature.m,losstab.m,losstab.fig,samplelib.m,samplelib.fig,save_sample.m,save_sample.fig)
