说明：  this code simulate sluted aloha protocol.

西电DSP实验课作业，主要包括MATLAB程序和C语言编的DSP程序，完成脉压，MTI,MTD的仿真，matlab和DSP分别调用(Western Electric DSP experimental course work, including MATLAB and C language program of the DSP program code to complete the pulse pressure, MTI, MTD simulation, matlab and DSP are called)

这是个循环的LMS算法，自适应课程的基本LMS算法过程~(This is a cycle of LMS algorithm, LMS adaptive algorithm for the basic process of course ~)

说明：  考虑到文件名长度，对文件名进行排序(Matlab) Matlab的sortrows完全排ASCII排序：10.jpg排在2.jpg前(Sorting file name think about the length of file name in MatLab program.)

base_band.rar文件解压后可以在matlab平台直接编译运行，实现通信系统的升余弦基带 成型处理，码元速率，采样率、滚降系数都可以灵活设置，特别方便学习通信的同学加深对基带信号的理解。(base_band.rar unzip the files can directly compile and run matlab platform to achieve communication system raised cosine baseband shaping processing, chip rate, sample rate, roll-off factor can be set flexibly, in particular, to facilitate students to learn to communicate better to the base band signal understanding.)

说明：  二次型准牛顿BFGS 公式,用于计算非线性函数(second type quasi-Newton BFGS formula used to calculate the nonlinear function)

Elnagar, G., et al. (1995). "The pseudospectral Legendre method for discretizing optimal control problems." IEEE Transactions on Automatic Control 40(10). 上述文章的算例2的仿真代码(Elnagar, G., et al. (1995). " The pseudospectral Legendre method for discretizing optimal control problems." IEEE Transactions on Automatic Control 40 (10). the simulation code of example 2 in the preceding article.)

万哲先的经典版本《代数和编码》，对于编码方面学习具有重要意义。(Zhe-Xian Wan classic version algebra and coding, for the coding to learn of great significance.)

平面刚架结构计算，能够输出结构内力和位移图形。但是在用之前要自己编辑节点信息和作用力信息(Plane frame structure calculation)
