说明：  模糊PID和传统PID的matlab实现(Fuzzy PID and conventional PID of the matlab implementation)

本程序特别适合于弹道计算等方面使用。比ODE45函数的速度加快了很多，且程序充分展示了Matlab向量运算的强大功能，以及编程的简单快捷。(This procedure is particularly suitable for use ballistic calculations and other aspects. ODE45 faster than a lot of functions and procedures for demonstrating the power of Matlab vector operations, and programming simple and quick.)

Compute descriptive and inferential statistics for circular or directional data

说明：  一本Matlab入门书籍，有Matlab基础或者无基础均可使用(This book is a short, focused introduction to MATLAB, a comprehen- sive software system for mathematics and technical computing. It will be useful to bothbeginning and experienced users.)

说明：  一种亚启发式(meta-heuristic)随机搜索算法，它从一个初始可行解出发，选择一系列的特定搜索方向（移动）作为试探，选择实现让特定的目标函数值变化最多的移动。(A meta-heuristic random search algorithm that starts with an initial feasible solution and selects a series of specific search directions (moves) as heuristics, selecting the moves that achieve the most changes in the value of a particular objective function.)
