这是一个用matlab实现的人脸识别的pca方法，正确识别率不错。(err)

基于Matlab的Morision方程计算波浪力(Based on the matlab morision equation wave force calculation)

北工商Matlab课件，对初学者很有用；用Matlab解方程的程序源代码以及有限差分方程源代码，希望对学习Matlab的小朋友有帮助(North Business Matlab courseware, useful for beginners with Matlab equations for the source code and the finite difference equation is the code, hope to help children learn Matlab)

说明：  是自己论文中编写的无线传感器网络中簇间路由分层次通讯方法的matlab仿真代码，可以直接出生存期图。很多论文都用这个思想。(Matlab simulation, an improved version of the leach agreement between the clusters, the passing of a hierarchical routing protocol to send a message, many papers use this thought, just write and run directly displayed a life cycle)

《精通MATLAB最优化计算（第2版）》(龚纯,王正林）附光盘源码(MATLAB for Optimization calculation(2rd))

电动执行机构是连接控制器与执行器(阀门)的部件，从控制出来的是离散信号，经零阶保持器后成为一个方波 信号，值都是阶跃跳动，而阀门的实际工作是有一定的行程时间的，即实际上阀门是不可能实现阶跃跳动的，故此需要一个电动执行器，将控制器的阶跃信号变为连续变化信号，假定阀门的行程时间与阀门开度变化成正比。(Electric Actuator is connected controller and actuator (valve) parts, from the control out of the discrete signal by zero-order cage became a square wave signal, values are step-beating, but the actual work of the valve there is a certain amount of travel time, that is, in fact the valve can not be achieved step beat, and therefore need an electric actuator, the controller of the step change in the signal into a continuous signal, assuming that the valve and the valve travel time changes in direct proportion to the door opening.)

用于speech enhancement的经典噪声估计源代码完整，可直接使用。(Classical speech enhancement for noise estimation complete source code can be used directly.)
