2-D FDTD TE code with PML absorbing boundary conditions Program author: Susan C. Hagness

This code can be use in inversion of seismic data.

考察ＬＭＳ算法的收敛性： （１） 步长因子的变化对算法收敛的影响； （２） 权初值的设置对算法收敛的影响 (Examine the convergence of the LMS algorithm: (1) changes in the step factor on the convergence of the algorithm (2) The right of the initial value set on the convergence of the algorithm)

说明：  换能器三维指向性仿真研究，主要是根据仿真笛卡尔坐标系下换能器阵列的声波指向性仿真(Simulation of three-dimensional directional transducer)

基于改进的matlab工具箱，主要用于遗传算法(Matlab toolbox based on an improved, mainly for genetic algorithm)

The kernel-ica package is a Matlab program that implements the Kernel ICA algorithm for independent component analysis (ICA). The Kernel ICA algorithm is based on the minimization of a contrast function based on kernel ideas. A contrast function measures the statistical dependence between components, thus when applied to estimated components and minimized over possible demixing matrices, components that are as independent as possible are found.

4. 数字信道化抗干扰反正，首先数字信道化多相滤波，差值的倍数为信道数的两倍，再采用AGC技术抗干扰。(4 digital channel anti-jamming anyway, the first digital channel of the polyphase filter, the difference in multiples of twice the number of channels, and then using the AGC technology anti-jamming.)

说明：  某班准备从5名游泳队员中选择4人组成接力队，参加学校的4×100m混合游泳接力比赛。 5名队员4种泳姿的百米平均成绩如下表，问应如何选拔队员组成接力队？(Classes to prepare a swim team from the five-member Select 4 relay team, participated in the School of the 4 × 100m relay swimming race mixing. Five members of the four kinds of strokes average 100 meters in the following table and asked how the composition of the selection of relay team members?)
