数学建模清华数模讲义\model10b (Mathematical modeling Qinghua digital-analog handouts model10b)

说明：  这个程序可以计算线性系统的计算的群延时.(this procedure can be calculated linear system of calculating the group delay.)

说明：  SVM用于模式识别 整理别人的代码（原来的是英文）所得： kernel.m用于内积矩阵的计算 svcplot.m用于绘图 svm168.m是主程序 testlin.m是采用线形内积函数的支持向量机应用的 文件 testrbf.m是采用RBF内积函数的支持向量机应用 的 文件 每个文件中都有说明。 仿真平台matlab7.0, 仿真全部通过 将所有文件拷贝到work目录下（注意不要直接将上层文件夹直接拷贝到work目录下，若那样操作，必须在matlab的file菜单中的set path中设置相应的路径）。 打开matlab，在命令窗口中输入 testlin或testrbf 即可查看结果。 (SVM pattern recognition for collating other people's code (the original is in English) from : kernel.m plot within the matrix for the calculation svcplot.m for graphics is the main svm168.m testlin.m procedure is used linear plot function within the SVM application documents testrbf.m RBF is using plot function within the SVM applications each file documents were described. Matlab7.0 simulation platform, all through the simulation of all the documents copied to the work directory (not directly to the attention of the upper folder directly copied to w contex directory, as if the operation, Matlab in the file menu on the set path corresponding set the path). Open Matlab, in the command window or imported testlin testrbf can see the results.)

MATLAB无线通信信道中Jakes模型仿真，可以显示Jakes信道模型的时域特性，幅度相位分布，自相关函数和多普勒谱(Jakes model generation wireless communication channel can display time-domain characteristics Jakes channel model, the amplitude and phase distribution of the autocorrelation function and Doppler spectrum)

功能：该程序用于仿真时间同步算法双向不等时间同步方法与无时漂往返校时方法（RTT）。输入：节点间距离、钟漂。输出：两幅同步误差比对图。(Features: The program for the simulation of two-way time synchronization algorithm for time synchronization methods ranging from no time when the drift from school method (RTT). Input: the distance between nodes, clock drift. Output: two synchronization errors of the map.)

动态规划的matlab程序，参看胡良剑等编《数学实验--使用MATLAB》P180，所举的例子，希望对初学者有用(matlab dynamic programming)

说明：  cma自适应恒模算法，由接受信号估计信道的自适应恒模算法(cma constant modulus adaptive algorithm, to receive signals from the adaptive channel estimate constant modulus algorithm)

用newmark-beta法计算单自由度结构输入地震动后的位移时程曲线，该函数可应用于各种周期的结构的反应，不存在中心差分法的问题 (newmark-beta method)
