说明：  mylsb.m是个非常完整的LSB密写源码并且密写和提取都在里面，图片我没上传，你只需要添加一个图片文件就可以了，记住图片必须是灰度图片，如果是RGB，我转换的代码也在里面很有意思哦。weipingmian.m是个提取图像位平面的程序，图片也是需要你自己加载，最后一个就是8*8块的图像DCT变换。(mylsb.m is a very complete source of LSB Steganography Steganography and extraction, and are on the inside, I did not upload pictures, you only need to add a picture file on it, remember the image must be a grayscale image, if it is RGB, I converted the code is also very interesting inside Oh. weipingmian.m is a program to extract bit-plane images, pictures, you also need to load the last one is 8* 8 DCT transformed image.)

matlab程序，生成小世界网络，可输入概率P，生成小世界网络模型(WS small world network)

有用的最小二乘法matlab的程序 有参考价值(Useful procedure for least squares matlab useful)

对FFT加汉拧窗操作，减少FFT产生的漏频效应和阑珊效应。(Add Chinese twist on the FFT window of operation, reducing leakage resulting FFT frequency effect and discouraged effect.)

课程实验程序，供大家参考。程序中有注释，简单易懂。(Experiment procedure, for your reference. The program have comments, simple and understandable.)

一种流形学习算法（很好用），一些自适应信号处理的算法，包含优化类的几个简单示例程序，基于SVPWM的三电平逆变的matlab仿真，使用matlab实现智能预测控制算法。( A fluid manifold learning algorithm (good use), Some adaptive signal processing algorithms, Optimization class contains several simple sample programs, Based on SVPWM three-level inverter matlab simulation, Use matlab intelligent predictive control algorithm.)
