《计算物理基础》是北师大彭老师写的，对学习用matlab解决物理问题很有帮助(this is a book about Computational Physics used matlab,the author is Mr peng and come from Beijing Normal University)

DSB的调制与解调MATLAB下的系统仿真(DSB modulation and demodulation system simulation under MATLAB)

说明：  边界元方法, 声学计算，声场仿真，声压值误差计算(BEM acoustics)

a Matlab Programme to simulate the cooperative communication technique AF amplify and forward between tow users and a destination

可以实现血管增强滤波，首先运行初始化文件，然后运行主函数文件（论文参考：Three Dimensional Curvilinear Structure Detection Using Optimally Oriented Flux）(Vascular enhancement filtering can be achieved, first run the initialization file, and then run the main function file)

MSK系统仿真利用simlink 其中加入了PCM编码解码(The MSK system simulation use simlink of which joined the PCM codec)

幅度调制解调：用两种方法实现解调包络检波和相干(Amplitude modulation and demodulation: two ways to achieve envelope demodulation and coherent demodulation)

1、利用simulink中sfunction方法建立航天器姿态动力学模型和运动学模型； 2、利用linmod对非线性模型线性化； 3、姿态模型线性化后，利用极点配置（pole）方法求取控制参数； 4、将控制参数带入非线性模型仿真控制效果。(One using simulink sfunction method to establish the dynamic model and kinematic model of the spacecraft attitude 2, the use of linmod linearization of the nonlinear model Attitude model linearization, the use of pole configuration (pole) is used to obtain the control parameters 4, the control parameters into the nonlinear model simulation control effect.)

源码给出了非线性LP问题的单纯形算法，程序分为5个.M文件，其中simple.m为单纯形算法，其他为调用文件，欢迎大家讨论下载。(Source LP problem given the nonlinear simplex algorithm, the program is divided into 5. M file, which simple.m for the simplex algorithm, the other for calling the file, please download the discussion.)

旋转矩阵和四原数之间的转换 用于坐标系之间的相互转换(Rotation matrix and the number of conversions between the original four)
