ITS ABOUT SOME BASIC MATLAB OPERATION

使用matlab来提取nastran生成的pch文件中的刚度矩阵与质量矩阵(Extraction of stiffness matrix and mass matrix)

说明：  一个很实用的MATLAB程序，望给需要的人带来方便(A very useful MATLAB program, hope to bring convenience to people in need)

绘制方向和速度矢量图，绘制等高线图以及动画(Direction and velocity vector drawing, drawing contour maps, and animation)

这是个MATLAB 得程序，有关的内容是 无线传感器网络得拓扑控制问题，一共有1个算法，希望对对无线传感器网络感兴趣的得大大们有一定的帮助。谢谢大家。 (it is the problem of topology control, if you are interested in it please download it . )

能够读取二维码，经过改造可以为己所用~~~~~~(The ability to read two-dimensional code, revamped for their own use ~ ~ ~ ~ ~ ~)

粒子群算法、遗传算法优化RBF径向基神经网络(Particle swarm optimization, genetic algorithm optimization RBF RBF neural network)

一维的有限差分源代码，，matlab，简单易学，方面使用，有限差分的优点就是计算简便高效(One-dimensional finite difference code)

EMD程序用于分解非线性非稳定性的曲线，对数据进行分解成本征模态函数，(The empirical mode decomposition and the Hilbert spectrum for nonlinear and non-stationary time series analysis)
