用四阶龙格库塔法求非线性系统的输入相应，同时用simulink建模比较。 (Using fourth-order Runge-Kutta method for the corresponding input nonlinear systems, and modeling using simulink comparison.)

information.m用来计算两个一维向量x和y的互信息。把压缩包中两个程序放在一起就可以运行(information.m used to calculate the two one-dimensional vectors x and y of the mutual information. The compressed package of two programs can run together)

本程序利用MATLAB进行数字信号的频谱分析，适用于DSP的初学者。代码里应用了矩形窗和汉明窗两种窗函数进行对比分析。(This procedure carries on the digital signal using MATLAB the spectral analysis, is suitable in the DSP beginner. In the code has applied the rectangular window and the hamming window two kind of window box number carries on the contrastive analysis.)

基于统计特征实现调制方式识别，供大家参考(stastical features based modulation recognition. )

一个matlab小程序，通过连续读取多幅图像创建一个视频，可以播放(a small procedure to read through a number of consecutive images to create a video playback)

Matlab Texture Extraction

说明：  用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

说明：  在MATLAB运行环境下，基于支持向量机的非线性系统辨识程序！(Run in the MATLAB environment, based on support vector machines for nonlinear system identification procedure!)
