四阶龙格库塔法的一个实例 希望能够帮助大家(Fourth-order Runge-Kutta method)

说明：  使用卷积法再现实验记录全息图，效果很好，欢迎下载(Convolution method for reproducing holograms)

This is the source code for 2D metrics in gird generation.

说明：  有压缩感知算法两种实现方式； 包括GPSR_BB和GPSR_Basic算法 有一个demo可以用来学习，部分内容根据自己的理解加了中文注释(There are two implementations of compressed sensing algorithm. Including GPSR_BB and GPSR_Basic algorithm There is a demo that can be used for learning. Some of the contents are annotated in Chinese according to their own understanding.)

4阶Nuttall窗128 点4-order卷积 matlab(Nuttall128 4-order convolution matlab)

说明：  用MATLAB实现的数字水印的DCT算法，还包括本次试验的实验报告，对算法有详细的解读！(Implemented using MATLAB DCT digital watermarking algorithm, also including the test lab report, a detailed interpretation of the algorithm!)

matlabcontourlet变换结合了不可分离的方向滤波组,具备小波所不能表达的多方向特性,能有效捕获自然图像的边缘轮廓信息。本文分析了图像ontourlet系数的统计特征,并利用广义高斯函数对各子带系数层进行建模。将此模型应用于基于VisTex的自建纹理图像库,采用矩匹配估计法,提取模型参数集,运用K2L (matlab)

双基地MIMO雷达利用ESPRIT算法实现目标二维方位角联合估计 (The ESPRIT algorithm bistatic MIMO radar goals 2D azimuth joint estimation)

说明：  本实验的目的是考虑不同维数下的高斯概率密度模型，用最大似然估计方法对其参数进行估计，了解最大似然估计方法。(The purpose of this study is to consider different dimensions of the Gaussian probability density model, using the maximum likelihood method to estimate its parameters to find maximum likelihood estimation.)
