说明：  用拉格朗日松弛法编写的matlab电力系统机组组合程序(Matlab power system unit commitment program written by Lagrange relaxation method)

说明：  CASIO 9860系列 计算本，国际友人编写，功能与PC的TXT差不多，但不支持中文(CASIO 9860 txtEditor)

基于matlab的高斯光束及传输特性分析。掌握高斯光束的光强分布特点及传播过程中光强的变化(Analysis of Gaussian beam and transmission characteristics based on matlab. Grasp the characteristics of intensity distribution of Gauss beams and the change of light intensity during propagation)

说明：  要研究一个新的重建算法-迭代软阈值算法，该算法根据所要解决的问题而确定一个阈值函数，并且可以将阈值算法和迭代算法有效的结合使用，明显的提高了重建信号的精度。本文主要对语音信号和带噪语音信号分别进行信号重建性能分析和研究。包括信号的稀疏性表示、观测矩阵的设计和选择、信号的重建过程及效果，通过实验仿真的波形图，进而对其和原语音信号不同之处进行了分析与对比。(To study a new reconstruction algorithm iterative soft threshold algorithm, this algorithm determines a threshold function according to the problem to be solved, and can effectively combine the threshold algorithm and iterative algorithm, which significantly improves the accuracy of reconstruction signal. In this paper, the performance of speech signal reconstruction is analyzed and studied. It includes the sparse representation of signal, the design and selection of observation matrix, the reconstruction process and effect of signal. Through the waveform of experimental simulation, it analyzes and compares its differences with the original voice signal.)

产生一组均值为1，方差为4的正态分布随机序列（1000个样本），估计该序列的均值与方差(A set of normal distribution random sequences (1000 samples) with mean value of 1 and variance of 4 is generated, and the mean and variance of the sequence are estimated)

% Input: XY(n,2) is the array of coordinates of n points x(i)=XY(i,1), y(i)=XY(i,2) % % Output: Par = [a b R] is the fitting circle: % center (a,b) and radius R % % Note: this fit does not use built-in matrix functions (except "mean"), % so it can be easily programmed in any programming language

该文件讲述了多种pid控制的原理，比如变积分控制等(This document describes the principles of many kinds of PID control, such as variable integral control, etc.)

说明：  锅炉汽包水位自适应模糊PID控制的模型与仿真，仿真能很好运行(Boiler bubble water control can realize the simulation of boiler water level, and the effect is obvious. (control))
