遗传算法解决求解带约束的优化问题明确遗传算法求解问题的一般思路和编码设计(Genetic Algorithm for solving constrained optimization problems with a clear genetic algorithm from the general ideas and Coding Design)

根据条形光波导折射率数据，分别针对宽高比a:b为1:1与 2:1两种情形，设计分析 ： 1. 满足单模与双模传输的 波导尺寸范围。（需要 给出色散曲线） 2. 针对两种情形，选取你 认为最佳的波导尺寸， 计算对应的模折射率。 （计算时假设上、下包 层均很厚）(According to the refractive index of the optical waveguide stripe of data, respectively, for an aspect ratio of a: b is 1: 1 and 2: 1 both cases, the design and analysis: 1. Meet single-mode and dual-mode transmission Bird size range. (need Given dispersion curve) 2. For both cases, you select That the best of the waveguide dimensions, Computes the corresponding mode refractive index. (Calculations assume that when the upper and lower package Layers are very thick))

自己做的一个滤波程序，相对比较简单，希望大家一起学习(A filter to do its own procedures, is relatively simple, I hope everyone learning together)

此为我老师写的RGELS算法，适合系统辨识的初学者(This is my teacher wrote RGELS algorithm, suitable for system identification of the beginners)

基于matlab编写的该程序，可以用于计算9层和9自由度建筑物模型在地震作用下响应。 (The program is written in Matlab based, can be used to calculate the excitation of 9 layer and 9 degrees of freedom model and input seismic building.)

针对离散系统的阶跃信号,正弦信号和方波信号的位置响应,设计了离散pid控制器(Step for discrete-time systems signal, sinusoidal signal and the square wave signal in response to the location, design a discrete controller pid)

in this image thresholding is done.image thresholding is getting by using seed polints concept
