MATLAB 求最小二乘法系数

一种轻量级的面向对象的C语言编程框架：LW_OOPC。LW_OOPC是Light-Weight Object-Oriented Programming in(with) C的缩写，总共一个.h文件，20个宏，约130行代码，非常的轻量级，但却很好的支持了很多面向对象的特性，比如继承、多态，可以优美的实现面向接口编程。这个框架系由台湾的高焕堂先生以及他的MISOO团队首创，之后由金永华继续改进优化，最后，经高焕堂同意以LGPL协议开源（开源网址参见后文）。 用C语言实现OO？我没听错吗？这听起来真是太疯狂了！… 大家都知道，C++支持了面向对象和面向泛型编程，比C要更强大些。那么，为什么要在C语言中实践面向对象呢？为什么不直接使用C++呢？ 希望这套宏，能够真正帮助到想用C语言写出面向对象代码的C程序员们! 源码包括几个使用这套宏的代码示例，可以认真钻研下。(A lightweight, object-oriented C language programming framework: LW_OOPC. LW_OOPC is an acronym for Light-Weight Object-Oriented Programming in (with) C, total. H file, 20 macro, about 130 lines of code, very lightweight, but very good support for object-oriented features, such as inheritance, polymorphism, and interface-oriented programming can be beautiful. This framework is the first team by of Taiwan Mr. Gao Huantang his MISOO continue to improve optimization, followed by Jin Yonghua, see below) agreed to LGPL the agreement open source (open source URL, GAO Huan-tang. Using C language implementation of Estimates of? I did not hear it? It sounds really crazy! ... As we all know, C support object-oriented and oriented generic programming than C to be more powerful. So, why do you want to practice in C language object-oriented? Why not just use C? I hope this set of macros, can really help to write object-oriented code C programmers who want to use the C language! Source includ)

说明：  3D-FDTD正演模拟程序，通过获取不同方向的电磁场分量来模拟全极化测量，对典型目标体进行了正演模拟，获得了不同位置、不同旋转角度下目标体的极化响应特征。(The 3D-FDTD forward simulation program simulates the full polarization measurement by obtaining the electromagnetic field components in different directions, carries on the forward simulation to the typical target body, and obtains the polarization response characteristics of the target body under different positions and different rotation angles.)

说明：  四旋翼无人机是一种具有六个自由度和四个输入的欠驱动强耦合、外型新颖结构简单的飞行器。由于其具有制造成本地、重量轻、体积小、操作简单、使用方便、隐身性好、对作战环境要求低的特点，使其能准确、高效的执行各种军事或民用任务，因此四旋翼无人机具有一定的军事和民用价值。本课题针对四旋翼无人机的特点和飞行原理，对其动力学分析以及运动控制的研究，利用牛顿—欧拉方程，建立了四旋翼无人机的动力学模型,并针对该模型设计了PID四通道控制系统,且在Matlab/Simulink仿真平台上,利用PID控制系统对四旋翼无人机进行仿真，完成了对四旋翼无人机运动控制和与地面运动物体的交会，仿真结果表明：仅仅通过改变四只旋翼的转速来改变升力，进而改变四旋翼无人机的姿态控制和位置控制，从而实现了四旋翼无人机的运动控制以及与地面运动物体的交会。(Height Control of Four-Rotor Aircraft)
