i4_choose

说明：  通过粒子群优化算法优化PID参数，该算法对pid控制器参数进行整定，pso能够对参数实现优化，且有良好的收敛性。(PSO algorithm tuning PID parameters)

用0－1test方法检测混沌的程序，程序完整，运行良好。(0－1Test)

说明：  主要介绍MATLAB7.0的工作环境、数组、矩阵、数值计算、M文件、图形用户界面设计、编译、接口及二维、三维图形绘制功能(MATLAB7.0 mainly working environment, array, matrix, numerical calculation, M files, graphical user interface design, compiler, interfaces and two-dimensional, three-dimensional graphics rendering capabilities)

这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊，定点，正割，二分法方法。这项工作是我的课程的一部分，在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察，你可以：例如，对于一个特定的公式，一种方法可能运行的迭代次数最少，而另一个将运行更多的迭代，但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)

3个CPU调度算法的simulation. 分别是Short Job First,High Return Ration Next, Round Robin. 模拟得到R,U,S等重要指标。(3 CPU scheduling algorithm of the simulation. Were Short Job First, High Return Ration Next, Round Robin. Simulated R, U, S and other important indicators.)

一个很好的扩频产生程序，可以帮你完成扩频通讯。(Spread spectrum have a very good program, can help you achieve spread-spectrum communications.)

Simulation of Quartz Crystal Resonator

对发生仿射变换的图像，通过计算仿射不变矩来获得图像的不变特征。(Affine transformation of the image occurs, by calculating the affine invariant moment to get the image of the same features.)

说明：  这个是编的BP神经网络的程序，对于初学神经网络的人有很好的借鉴(This is a series of BP neural network program, for the beginner neural network is a good reference)
