固体力学的大作业，有限元法计算阶段梁，包括了计算单元应力。(Finite Element Method matlab program, an example of 1D step beam element. Including calculation of elemental stress.)

关于LSB的数字水印源代码，大家可以参考一下，欢迎共享(the code about the digital watermark of LSB，using matlab)

说明：  产生一个4096点的正弦加白噪声序列，且产生该序列的幅度谱(Produce a 4096 point increase in white noise sinusoidal sequence, and generate the sequence of the amplitude spectrum)

双向协作通信的中断概率仿真，结果和《Performance Analysis of Two-Hop Relayed Transmissions over Rayleigh Fading Channels》里面的结论完全一样。可以得到三幅图。(Two-way collaborative communication outage probability simulation， results and 《Performance Analysis of Two-Hop Relayed Transmissions over the Rayleigh Fading Channels 》，the conclusion is exactly the same. You can get three in Fig.)

说明：  图像二值化，边缘提取包含sobel、log、canny等方法，还有图像直方图均衡化，对比度增强等(Image binarization, edge extraction includes sobel, log, canny and other methods, as well as image histogram equalization, contrast enhancement and so on.)

空间谱估计算法，是研究信号噪声比的。效果还可以(Spatial spectrum estimation algorithm, is to study the signal-noise ratio. Effects can also be)

matlab 专业设计 源于课本的原文件 适合于编程人员(matlab professional design textbooks from the original document is suitable for programmers)

解压缩文件，将三个文件放在同一路径下，打开MATLAB，运行example_09.m文件。即可利用鼠标进行绘画。(Unzip the files, three files on the same path, open the MATLAB, run the example_09.m file. You can use the mouse painting.)

聚类分析中的划分聚类算法的k-means算法（随机选取矩阵数据）(Partition clustering algorithm in clustering analysis of k- means algorithm (random matrix data))

异步机直接启动最基本的仿真模型，希望对大家有用(Asynchronous machine directly start the basic simulation model, we hope to be useful)
