说明：  计算在一个矩形里，用同等大小圆来覆盖这个区域，所需要的最小圆个数，我已经运行过(Calculated in a rectangle, the circle with the same size to cover the region, the minimum required for a round number, I have to run-off)

基于卡尔曼滤波的无线传感网络目标跟踪算法，包括卡尔曼、扩展卡尔曼、无迹卡尔曼(Wireless sensor network target tracking algorithm based on Kalman filter, Kalman, extended Kalman, unscented Kalman)

循环自相关函数工具箱，还带有自己编写的代码，ex1-7．(Circulating auto-correlation function of the toolbox, but also prepared with its own code, ex1-7.)

说明：  Hopfield网络仿真实例参考:包含Hopfield网络设计实例及仿真源程序.(Hopfield network simulation reference: examples include the design and simulation of Hopfield network source.)

利用二维有限差分法对单脊波导TM模进行计算。通过调整网格数目观察计算结果的精度，可以设定出最优的网格数目，然后改变波导中脊的尺寸，观察最低两个TM模对应的截止频率的变化规律，最后给出对应的横截面电场、磁场分布图(The two-dimensional finite difference method to calculate the single-ridge waveguide TM mode. The optimal number of grid can be set by the accuracy of the adjustment of the calculation result of the grid number observed, and then change the size of the waveguide ridge observed the lowest two corresponding to the TM mode of the cutoff frequency of the variation, and finally to give the corresponding cross cross-section of the electric field, magnetic field maps)
