对貂和麝鼠之间的关系用VARMA建立状态空间模型(VARMA modeling：interaction between minks and muskrats)

MATLAB语言的发展，基本语法，开发环境和工具，数据分析库datafun(MATLAB language development, basic grammar, development environment and tools, data analysis library datafun)

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.

贝克汉函数方便解决一些复杂函数，可以调用作为子函数来使用。(Beckham convenient function to solve some complex functions can be called as a subroutine to use.)

产生随机数的方法很多，很多软件自己就有产生随机数函数，本程序用的是乘同余法产生随机数，经对比，效果比matlab自带的要好。(Many methods of generating random Numbers, this procedure is by using congruence method generating random Numbers.)

自己编写的数字滤波器工具箱，界面和功能均参照MATLAB中的FDATOOL工具箱。能实现FIR，IIR各种数字滤波器的设置。(A program designed in MATLAB GUIDE with the interface and function of FDATOOL in matlab. )

matlab调用ansys的例子，适合初学者。(matlab call ansys example, suitable for beginners.)

用Jacobi Gauss-seidel SOR迭代法求解线性方程组(With Jacobi Gauss-seidel SOR iterative method for solving linear equations)

这是粒子群的算法,采用matlab实现.方便大家学习.(this is PSO arithmetic for matlab implemnet.)

0-40的立方，实现输入任意0-40数就可以得到数的立方值(0-40 of the cube, the number of the input an arbitrary 0-40 can get the value of the number of cubic)
