利用matlab编写的有限元程序 beam(Finite Element Analysis)

在matlab7.8版本上编译通过。 利用matlab的滤波器工具箱函数实现对直扩扩频通信过程的仿真模型，可以简单设定功率控制，多径传输，多值干扰等过程。(This program is compiled successfully in Matlab7.8 platform. With the matlab Filter Toolbox funtion to simulate the process of spread spectrum transmission. The simple option such as power control,multiprocess and multiaddress nterference can be set in this program。)

copulas参数估计方法的源代码。copulas为一种统计方法。(copulas parameter estimation method of the source code. copulas is a statistical method.)

车辆四自由度模型的MATLAB分叉图程序，简单明了。用来做分叉图分析(MATLAB bifurcation diagram program four degrees of freedom vehicle model, plain and simple. Used for bifurcation diagram analy)

说明：  分割对比实验：软硬ESFCM分割结果是差不多的，但是，软ESFCM的执行时间要比硬ESFCM少很多(Split comparative experiments: hardware and software ESFCM segmentation results are similar, but the execution time of the soft ESFCM much less than the hard ESFCM)

说明：  读取地震数据的道头字并画出剖面图, 没有读出所有的道头，只读取了几个角为重要的(read headers of seismic data and draw the profile)

北京航空航天大学出版的matlab从零到进阶第二章的示例程序(Beijing University of Aeronautics and Astronautics matlab published the first chapter from zero to advanced sample program)
