数字水印的入门代码，包括LSB DCT CDMA DWT,在原有收集上加了详细的注释，易于学习理解(Watermarking entry code, including LSB DCT CDMA DWT, add in the original collection of detailed notes, easy to learn to understand)

基于Matlab2007的美军F16战斗机的非线性模型 (Based on the U.S. F16 fighter Matlab2007 the nonlinear model)

体视化引擎创建了整洁的结构，并给出一个GUI调用的实例。(Volume Visualization Engine to create a neat structure, and give examples of a GUI calls.)

说明：  此代码利用高斯牛顿迭代法，对非线性函数进行参数辨识。可以对传递函数通过阶跃响应实验得到的数据进行迭代获得传递函数的参数(The code uses the Gauss-Newton iteration method to identify the parameters of the non-linear function. The parameters of the transfer function can be obtained by iterating the data obtained from the step response experiment of the transfer function.)

说明：  时移多尺度排列熵一种应用于非线性非平稳信号的特征提取方法，能够有效的处理信号特征信息。(Time-lapse multiscale permutation entropy is a feature extraction method applied to non-linear non-stationary signals, which can effectively process signal feature information.)
