overlap_add

gives a rough jpeg based coding routine that enables the user to convert and compress any image into jpeg format

说明：  对初学MATLAB的同学有极大的帮助，本书实例较多可以更好的掌握(MATLAB beginner students to the great help, this book can better grasp the larger examples)

包含几个主成分分析方法的程序以及主成分分析法的讲解。(Contains several principal component analysis program and principal component analysis method explain.)

扩展卡尔曼轨迹追踪的仿真程序，输出目标的实际位置，及误差曲线。(Extended kalman tracking simulation program, the actual position of the target output, and error curve. )

EM算法的MATLAB实现,EM算法是HMM中用于随机过程模型参数训练的经典算法(the inplement of algorithm EM with MATLAB，the algorithm is a claasical mathod which is used to train the patameter of the HHM model.)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

HDB3扰码技术的matlab编程实现，自己的论文整理，计算机原理必备(HDB3 scrambler technology of matlab programs, their papers, computer principle is necessary)

Economic load dispatch using Artificial bee colony optimization

这是一个由我本人亲自编写的提取图像特定部分的MATLAB程序。通过使用这个函数，你可以轻而易举地将图像的特定位置用白色矩形线框加以圈定、显示。(If you want to circle the specific area of an image, this little program is much more practical and convenient, thus will help you to mark any area of the image with with rectangle.)

子彈 可以用C++ code做出子彈並放進射擊遊戲。(Bullets can make use C++ code and put a bullet shooter.)
