本文章中介绍了行业软件ansys的基础知识，基本操作以及一些高级的应用，对于刚接触ansys的人是很好的入门材料(This article describes the basics of the industry software ansys, the basic operation and some advanced applications, for people new to ansys is a good introductory material)

In histogram equalization we are trying to maximize the image contrast by applying a gray level transform which tries to flatten the resulting histogram. The gray level transform is a scaled version of the original image s cumulative histogram. That is, the graylevel transform T is given by T[i] = (G-1)c(i), where G is the number of gray levels and c(i) is the normalized cumulative histogram of the original image.

用c-mex文件编写的s函数，生成一个指令信号，其实就是一个分段函数(Preparation of documents with the c-mex s-function, generates a command signal, in fact, a sub-function)

针对粒子群算法存在局部最优，易陷入局部最小值的问题，自适应权重粒子群优化算法(For particle swarm optimization, there are some problems, which are easy to fall into local minimum, and the adaptive weight particle swarm optimization algorithm is easy to fall into local minimum.)
