Arnold猫脸变换，matlab源码。(Arnold cat face transformation, matlab source.)

滤波代码，通过虚拟的动态窗口迭代过滤，剔除地物保留地表信息。(filter code，keep the ground information through a virture moving window.)

了解matlab的GUI是如何使用。并对发动机进行交互界面开发。(Understand how to use matlab GUI is. And the engine interface development. )

求解微分方程（这里指的是常微分方程）指含有一次、二次、乃至高次微分未知数的方程。是解决偏微分方程、数理方程的基础。有许多特殊函数，都是为了无法得出多项函数或超越函数型式的解析解的微分方程而定义出来。这些特殊函数之所以重要，是因为它们描述了自然界中的某些现象，例如，电子的活动、鼓皮的振动、钟摆的摆动等等。(Solve differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on. )

一种非线性PID控制算法在卡车ABS中的应用及仿真研究，提出NPID控制器的建模()

em算法计算混合高斯模型的参数估计，极大似然，EM算法用于K均值问题的参数估计。MATLAB实现有代码(em algorithm Gaussian mixture model parameter estimation, maximum likelihood parameter estimation for K-means problem EM algorithm. MATLAB implementation code)

说明：  有源电力滤波器是用于动态抑制谐波、补偿无功的新型电力电子装置，控制并主动输出电流的大小、频率和相位，并且快速响应，抵消负载中相应电流，实现了动态跟踪补偿，而且可以既补谐波又补无功和不平衡。(APF:Active power filter)

This code calculate the PSNR between the original and the distored image, and give the value of this PSNR.

说明：  以整数线性规划方法解决火电机组机组组合问题。包括爬坡、启停约束等。以最小化运行成本为目标。(Integer linear programming (ILP) is used to solve the unit commitment problem of thermal power units. Including climbing, start-stop constraints and so on. The objective is to minimize operating costs.)
