说明：  设计低通IIR滤波器；并将此低通滤波器映射为高通、带通或带阻滤波器。并验证变换后的滤波器是否满足指标。并求输入x(n)=[cos(w1n)+cos(w2n)]u(n)经过系统后的输出y(n)(Low-pass IIR filter design and mapping this low-pass filter high pass, band pass or band stop filter. And verify whether the filter transformation to meet the target. And to seek input x (n) = [cos (w1n)+ cos (w2n)] u (n) through the system output after the y (n))

EKF的经典程序，可运行不同模型的EKF,算法精简，准确(The classic procedure of the EKF, can run a different model of the EKF algorithm streamline accurate)

This matlab code includes the solution for root off a polynomial by Bairtow method .....

旋转Y切-弹性压电薄膜，谐振器的特性计算及分析，用MATLAB编程计算。(Rotated Y-cut- elastic piezoelectric thin film resonator characteristic calculation and analysis, calculated using MATLAB programming.)

蚁群算法，对无人机路径进行有效规划，避免无人机相撞事故(Colony algorithm, effective UAV path planning to avoid drone crash)

这是一个通信中交织器的程序 自己用过了还可以使用 通过将图像中的集中错误分散化来实现的(this is a program about Intertexture implement)

说明：  matlab程序模拟微分方程。各种流行的系统显示混沌运动特征。(This toolbox contains the functions which can be used to simulate some of the well-known fractional order chaotic systems, such as: - Chen s system, - Arneodo s system, - Genesio-Tesi s system, - Lorenz s system, - Newton-Leipnik s system, - Rossler s system, - Lotka-Volterra system, - Duffing s system, - Van der Pol s oscillator, - Volta s system, - Lu s system, - Liu s system, - Chua s systems, - Financial system, - 3 cells CNN. The functions numerically compute a solution of the fractional nonlinear differential equations, which describe the chaotic system. Each function returns the state trajectory (attractor) for total simulation time. )

经典的三人过河问题，利用MATLAB求解，最后的出决策矩阵，由此安排过河方案！(The classic three-river issues, the use of MATLAB to solve, the last of a decision matrix, thereby arrange the program across the river!)
