说明：  基于matlab的GUI界面设计的成绩管理系统，可以直接用！(Based on the matlab GUI interface design of the performance management system )

This code is a demo of using Genetic Algorithms (GA) to solve a simple constrained multi-objective optimization (MOO) problem.

简单介绍雨滴的形成，运用流体力学相关知识，分析了雨滴下落所受的黏性阻力和压差阻力，考虑雨滴在空气中下落半径增加对雨滴速度的影响，得出了雨滴下落速度和雨滴半径的关系，对雨滴下落的收尾速度进行了一般的讨论。(Brief rain formation, the use of the knowledge of fluid mechanics, analysis of viscous drag and pressure drag the raindrops whereabouts suffered consider raindrops in the air, the whereabouts of the impact of increasing the radius of raindrops speed, to draw raindrops falling speed and raindrops radius the general analysis of the relationship between the terminal velocity of raindrops whereabouts.)

这是国标数字电视地面传输标准里信道编解码器的MATLAB程序，用的是LLR-BP的解码算法，请大家指正。另有根据国标生成的生成矩阵和校验矩阵稍后传上来(This is the national standard of digital TV terrestrial transmission standard in channel codec MATLAB program, using the LLR-BP decoding algorithm, please correct me. Otherwise in accordance with GB-generated matrix and calibration matrix generation later Chuan-up)

simulation of optic fiber link budget analysis is to feed input as attenuation loss, connection loss , system margin, transmitted power and length of the fiber
