matlab加权 voronoi 剖分网格代码。方便简单。 适合入门与科研应用。(matlab mesh generation code. Convenient and simple.voronoi )

利用matlab写的检测椭圆参数的算法，利用hof变换以及相关的椭圆特征提取算法，能将任意的椭圆长短轴参数以及椭圆心进行标注出来(The use of matlab to write detection algorithm of elliptic parameter, using the hof transformation as well as relevant ellipse feature extraction algorithm, can be arbitrary elliptic axle parameters of the ellipse and heart to be marked )

it is a very simple and helpful document and source code for image compression

说明：  针对污水处理系统的多变量、非线性、时变性与随机性等特点，介绍了专家系统的结构和特点及其在污水处理领域的应用研究现状，分析了其存在的问题。结果表明，国外专家系统发展迅速，并且应用领域遍及污水处理系统的各个方面，国内尚处于起步阶段。最后提出了在污水处理领域专家系统应用研究的发展方向。(Sewage treatment system for multi-variable, nonlinear, time variability and random other peculiarity of the structure and characteristics of expert systems and its application of sewage processing status, and analyzes its problems. The results show that the rapid development of foreign expert systems, and applications across all aspects of sewage treatment system, domestic still in its infancy. Finally, an expert in the field of wastewater treatment system application development direction.)
