模糊C均值聚类的例程，matlab环境下(Fuzzy C-Means clustering routines, matlab environment)

这是一个关于数字信号处理的PPt基础课件。(it is a lession for dsp base)

matlab源程序,边界跟踪 （bwtraceboundary函数）(Matlab source, boundary tracking (bwtraceboundary function) )

说明：  上传的是Levenberg-Marquardt算法的Matlab程序(Upload is the Levenberg-Marquardt algorithm in Matlab)

dijkstra计算最短路径，算法在优化、图像处理、网格处理等相关领域有非常广泛的应用，希望能借此机会了解其实质内容，并灵活应用其到所学领域中。(dijkstra calculate the shortest path algorithm optimization, image processing, mesh processing and other related fields have a very wide range of applications, hoping to take this opportunity to learn about its substance, and the flexibility to apply their learning to the field.)

this code is about different types of digital communications

说明：  利用MATLAB语言调节GUI窗口尺寸，有简单的示例(Adjusting the size of GUI window using MATLAB language)

matlab 下的遗传算法源码，可以应用到大部分情况的全局寻优。(By using matlab ，I have provided a genetic algorithm source code, which can be applied to most cases of global optimization.)
