包含两个程序,以蛙跳积分法绘制henon-heiles演化方程的时间演化图,x-y,x-vx,y-vy相图和三维庞加莱截面图.( Contains two procedures to leapfrog integration time evolution plotted in Figure henon-heiles evolution equations, xy, x-vx, y-vy phase diagram and three Weipangjialai-sectional view.)

使用Matlab AR模型的LPC函数来做特征值提取。传统方法中LPC一般用来做语音处理。这里每100个数据来做LPC，用获得的N阶参数来作为振动信号的特征值。这样10000个样本可以获得100个特征值样本集。用这些样本集可以做神经网络分类(Matlab AR model LPC function to do eigenvalue extraction. Conventional method LPC generally used for voice processing. Do LPC, where each of 100 data is obtained N-order parameter as the characteristic values ​ ​ of the vibration signal. So 10000 samples can be obtained the 100 the eigenvalue sample set. Neural network classifier can do with these sample sets)

自己编的5种调制信号，借鉴了主成分分析算法（PCA），用于信号特征提取、信号消噪。( Own five modulation signal, It draws on principal component analysis algorithm (PCA), For feature extraction, signal de-noising.)

说明：  use for research in the image processing techniques in medical image processing

The document contains many sources for computing FIR and IIR, also there are many pictures of the results.
