这是一个图像分割程序，基于snake方法，对初始位置选择要求较高，在matlab环境下调试运行(This is an image segmentation procedures based on the snake, location of the initial demand for a higher choice, In Matlab environment debugging operation)

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)

非线性滤波的程序，里面包含扩展卡尔曼滤波和无迹卡尔曼滤波滤波，可应用于很多非线性系统(Nonlinear filtering process, which includes extended Kalman filter and unscented Kalman filter filtering can be applied to many nonlinear system)

On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M1.mat. Load this workspace and plot the speech waveform labeled speech1 10k. This speech segment was taken a vowel sound that is approximately periodic, 25 ms in duration, and sampled at 10000 samples/s.
