在 matlab 中的蝙蝠算法

calculation of one and two dimensional FDTD. 1D and 2D FDTD

说明：  DSP 的 matlab 仿真，主程序部分，已经通过编译。(DSP Matlab simulation, part of the main program, the compiler has passed.)

EGO算法是基于kriging模型的全局优化方法，不通过函数而是通过样本模型寻优，文件给出实例，加载相应的工具箱即可。(EGO algorithm is a global optimization method based on Kriging model. Instead of function, it is optimized by sample model. The example is given in file, and the corresponding toolbox can be loaded.)

自己写的几个matlab的函数，自己处理数据是常用。有滤波函数、平移函数等。处理后新生成的数组和原数组大小相同，行列特性也相同。(Himself wrote several matlab functions, deal with their own data is commonly used. There are filtering function, translation function, and so on. The new array is generated after treatment and the original array the same size, the ranks of features are the same.)

Quartic Spline weight function from "An Introduction to Meshfree Methods and Their Programming [G.R. Liu, Y.T. Gu] " the orginal code is in fortran but this code is in matlab

应用背景一般输入信号x（t）通过一个线性时不变系统称为不失真的如果它的形状是相同的输入信号x（t）。在数学上，输出（吨）有以下的形式：Y（t）= x（t−TD），（1）其中K是增益和TD是时间延迟。在频域中可以很容易地得到失真的条件下的传输。为了获得这些条件，我们采取傅立叶变换（英尺）的（1）在（吨）：Y（F）= KX（F）E−J2  FTD，（2）（女）和×（英）指的是（吨）和×（吨）。记得一个LTI系统的频域输出可以写为（女）=（女）（女），（3）其中H（f）表示的脉冲响应h（t）的FT的LTI系统。关键技术增加幅度失真和相位失真。这是通过使用MATLAB。通信系统实验室。
