PID控制程序，matlab编写，适合初学者（2）(PID control procedures, matlab prepared for beginners (2))

说明：  图像空域变换增强技术实践,附带matlab code(Image enhancement technology transform the practice of airspace，Matlab code attached)

先进PID控制 MATLAB仿真 第2版 刘金琨等编著和书中的所有程序，模糊控制及其MATLAB应用 张国良，是很好的学习模糊控制的资料。(Advanced PID control of MATLAB version 2 Jin-kun liu huang, and all the procedures of the book, such as fuzzy control and its application MATLAB RON cheung, is a very good learning fuzzy control information.)

一个50行的简短Matlab有限元程序，求解三维线弹性问题。执行fem3d.m即可。(A brief 50-line Matlab finite element program for solving three-dimensional linear elastic problem. Executive fem3d.m .)

一种人工免疫系统算法的源程序，适合绝对其他算法的改进。(An artificial immune system algorithm source code for the absolute other algorithm.)

单步单纯型法，输入为系数矩阵，右端向量，目标函数系数向量，基变量下标，非基变量下标和基变量初始值(Step simplex method, the input for the coefficient matrix, right vector, the objective function coefficient vector, the base variable subscript, superscript and the non-basic variable initial value of base variable)

可实现光流、惯性、地磁组合导航的扩展卡尔曼滤波算法(This program can realize the integration if optical flow/INS/magnetic.)

核查的关键在于对核材料属性准确、有效地识别[1][2]。利用252Cf作为随机脉冲中子源，对其入射核材料所产生的诱发裂变中子脉冲信号进行采集、处理和分析，得到自相关、互相关、自/互功率谱、功率谱密度比等一系列参数，从而反演核材料内部的反应性的情况，便可用于分析和识别核材料，其基本原理就是252Cf中子源驱动噪声分析测量法[(The result shows that the trained Elman neural network is able to identify the characteristics of correlation function, to distinguish different concentrations, and the average recognition rate reaches 90 , with high robustness.)

仿真分析了FFT的补零、泄露、加窗、以及FFT分辨率等问题(Simulation analysis of the FFT of zeros, leakage, windowing, and FFT resolution issues)

ESPRINT谱估计，计算DOA，可以与capone进行对比。(ESPRINT spectrum estimation calculates DOA, with capone comparison.)
