PID仿真程序，只需要人工修改PID参数，及根据自身情况修改模型参数就可以轻松实现PID仿真。(PID code in matlab)

说明：  模糊综合评判计算程序 模糊综合评判的过程：1、灰色关联分析，求权重（程序见Relation）；2、模糊聚类分析，划分等级（程序见F_class）；3、隶属度计算，求隶属函数（程序见Subjection和subject）；4、模糊综合评判，计算各单元等级（程序见F_judge）。(Fuzzy comprehensive evaluation matlab code The process of fuzzy comprehensive evaluation: 1. Grey relational analysis to get weight (see Relation for program); 2. Fuzzy clustering analysis to divide ranks (see F_class for program); 3. Membership degree calculation to get membership function (see Subjection and subject for program); 4. Fuzzy comprehensive evaluation to calculate each unit grade (see F_judge for program).)

本文章是matlab中robotics工具箱的介绍(This article is an introduction matlab toolbox in robotics)

this is new approach for fuel cell control.it is really helpfull.

keep useful variables in the matlab workspace

说明：  用于模拟光纤中的非线性薛定谔方程，包含了色散、非线性等现象的模拟，对与想了解脉冲在光纤中的传输变化非常有帮助(Used to simulate the optical fiber in the nonlinear Schr&ouml dinger equation, including the dispersion, nonlinear phenomena such as analog, pulse on and want to understand changes in the transmission fiber is very helpful)
