Electromagnetic Simulation using the FDTD method 实例 2-3 frequency_dependent_media ，用matlab重新编写(Electromagnetic Simulation using the FDTD method example 2-3 frequency_dependent_media flux density ，rewriting in matlab)

单缝衍射，白光重现。大学物理很好的演示示例。自编。(Single slit diffraction, the white light to reproduce.University physics demonstrating example very well.The self-made.)

DOA estimation methods

对matlab数学建模进行了系统的介绍。并配有大量的案例一共学习。适用于初学者(Matlab mathematical modeling for the system were introduced. And total Peiyoutailiang case study. For beginners)

Galerkin方法,这是一种真正的无网格方法.这种方法采用移动最小二乘函数采近似解变量,并且采用移动最小二乘近似函数的权函数作为加权残值法的权函数.文中对形成的离散动力学方程用Newmark方法求解(Galerkin method, this is a real meshless method. This method adopts moving least squares in function approximation solution variables, and adopts moving least squares approximate function of weight function as a weighted residual method of weight function. In the paper, the discrete dynamic equation formed with Newmark method to solve)

基于前推回推法的matlab源程序基于前推回推法的matlab源程序基于前推回推法的matlab源程序(Before pushing back the method based on matlab source Before pushing back the method based on matlab source )

This package contains some matlab file for user defined array pattern. Also contain codes for directivity and gain.

说明：  这个水印一般般利用DWT变换和DCT变换嵌入水印，加上了Arnold变换使图片水印的抗MP3压缩攻击有所提高。(The watermark in general as the use of DWT transform and DCT transform embedded watermark, coupled with the Arnold transform to image watermarking against MP3 compression attacks increased.)

说明：  批量下载图片，可以从FLICKER上下载图片(Batch download pictures, download pictures from FLICKER)
