netcdf插件安装和.nc格式数据的读取,主要操作mexcdf53.dll和netcdf.dll文件,适于从事海洋和大气专业的的数据格式.作者在实际中用matlab处理了一些此类数据，简单说来就是安装一个插件即可.现将我们的方法具体地写出，以供参考(NetCDF installation and plug-ins. nc format to read data, the main operating mexcdf53.dll and netcdf.dll document, suitable for marine and atmospheric data format professional. Author matlab used in the actual treatment a number of such data, simple to say that you can install a plug-in. The way we write specifically for reference)

针对频率周期振荡的振动系统讨论自适应控制问题,在频率跟踪的基础上对频率变化的振动响应进行控 制,给出相应的估计、滤波与控制方法。首先在子空间辨识原理的基础上,通过测量信号自相关序列的递推运算获得信号 频率 然后根据估计频率实时调整带通滤波器的中心频率,使其跟踪信号频率,实现信号分量的跟踪滤波 最后在LMS方 法的基础上构造对信号分量进行控制的自适应控制器。(The adaptive vibration control of systems excited by forces of periodically varying frequencieswas dis- cussed. The presented adaptive controlwas realized on the basis of tracking of time-varying frequencies and amethod for online frequency estimation, filtering and controlwas proposed. Based on the principle of subspace identification, the time-varying frequencieswere estimated from the recursively computed autocorrelation ofmeasured signals. )

高斯混合模型的matlab实现，基础知识，适合初学者(Gaussian mixture model matlab achieve basic knowledge for beginners)

这个工具箱是对水平集方法的matlab程序的搜集。这些程序应用数值算法在任一维度来近似基于时间变化的汉密尔顿雅可比偏微分方程的解。汉密尔顿雅可比偏微分方程常用动画演示动态隐式曲面，计算流体动力学，并且它是独立在最优控制，微分博弈机器人，金融数学，连续的可达性等兴趣领域。(The Toolbox of Level Set Methods (ToolboxLS) is a collection of Matlab routines that implement numerical algorithms to approximate the solution of the time-dependent Hamilton-Jacobi (HJ) partial differential equation (PDE) in any number of dimensions. The HJ PDE is often used for simulating dynamic implicit surfaces in animation and computational fluid dynamics (CFD), and it is of independent interest in areas of optimal control, differential games, robotics, financial mathematics, continuous reachability, etc.)
