用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，(Using matlab realize the number of LSB-based watermarking algorithm. Algorithm can be embedded BMP gray image watermark, watermark information for the binary image, and its expansion to the original image the same size, the repetition of embedding, improve robustness. At the same time algorithm PSNR values are given to evaluate the effect of watermark images,)

利用matlab实现图片的编辑，图像的亮度调节，缩小和放大，格式的转换等。(Using matlab realize image editing, image brightness adjustment, zoom in and out, format conversion and so on.)

使用矩量法计算微带天线的特征阻抗，用户需自行更改其中的天线的几何尺寸和工作频点．(Calculated using the method of moments microstrip antenna characteristic impedance, the user need to change one of the antenna geometry and frequency.)

数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改 第三章(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which part of the program were modified Chapter)

采用TLS-ESPRIT算法，进行空间阵列信号的频率估计(With TLS-ESPRIT algorithm to estimate the signal frequency space array)

发射线性调频信号，假定三个点目标，模拟信号碰到目标返回后的回波。(Transmit chirp signal, assuming three points target, the target return echo analog signal after the encounter.)

用matlab书写的H.261代码，实现了视频编解码整个过程， 值得初学视频编码的同学参考(Matlab code written using H.261, the video codec to achieve the whole process worth novice video coding reference for students)

《有限单元法教学实习程序汇编》内容简介 汇编了四个有限单元法程序（平面刚架计算程序FEM2.FOR、平面三结点三角形单元计算程序FEM3.FOR、平面四结点等参数单元计算程序FEM4.FOR和空间八结点等参数单元计算程序FEM8.FOR）。其中FEM2.DAT、FEM3.DAT、FEM4.DAT和FEM8.DAT为四个算例的输入数据文件。为了便于读者读懂程序，对每个程序做了详细注解。(A compilation of four finite element method program (plane frame calculation program FEM2.FOR, flat three node triangular element calculation program FEM3.FOR, flat four nodes and other parameters and space unit calculation program FEM4.FOR eight nodes, etc. parameter unit calculation program FEM8.FOR). Which FEM2.DAT, FEM3.DAT, FEM4.DAT and FEM8.DAT four examples of input data files. To help readers understand the program, for each program in detail annotations.)
