A programmable-logic controller (PLC) is a compact computer-based electronic system that uses digital or analog input/output modules to control machines, processes, and other control modules. A PLC is able to receive (input) and transmit (output) various types of electrical and electronic signals and use them to control and monitor practically any kind of mechanical and/or electrical system.

经典的基于策略迭代和值迭代法的动态规划matlab代码，实现机器人的最优运输(The classic dynamic programming matlab code based on policy iteration and value iteration method realizes the optimal transportation of the robot.)

本程序实现了matlab自带函数imfillter的功能，是.m文件的形式，参数和imfilter一样可选。程序附有图片，并且在程序最后使用imfilter，便于直接对比观察处理效果。注：本程序是读入RGB图像，转换成灰度图进行处理。(This program implements the function of matlab own function imfillter is. M file in the form of the same parameters and imfilter optional. Procedures with pictures, and last used in the program imfilter, for direct observation of treatment effect contrast. Note: This program is read into the RGB image into grayscale processing.)

Jacobi矩阵一般是坐标变换时用的——这个坐标系的坐标依次对那个坐标系的坐标求偏导数即得Jacobi矩阵。积分时从直角坐标变到球坐标、极坐标肯定要在积分号里乘上Jacobi矩阵的行列式。 若其特征值全为正，则此Jacobi矩阵正定，即它的任何二次型都大于零。并且如果是对称Jacobi矩阵，还可以实相合于一个单位阵。是比较强的条件。矩阵A的特征值是这个关于x的方程的所有根 det(A-xI)=0(Jacobi)

基于matlab的同步风力发电模型仿真，可以放心下载使用(Matlab - based synchronous wind power model simulation, you can rest assured to download)

在多目标优化算法中，算法的好坏需要通过多种指标来恒定，HV指标是一个综合评价指标，且不需要真实帕累托前沿即可对多种算法进行对比，HV值越大则算法效果越好
