频率估计的ESPRIT方法,实现频率的精确估计，并可推广到空间到达角的估计(frequency estimation with ESPRIT method)

说明：  对400幅灰度图像用分块PCA的方法进行压缩，进行通信时只用传输主元和特征向量。其中，pcaxiefangcha.m用于图像压缩，imresume.m用于图像恢复和部分图像的显示，chaweight.m用于绘制特征值比重-主元个数关系图，crdraw.m用于绘制压缩比-主元个数关系图，psnrdraw.m用于绘制总误差PSNR-主元个数关系图，psnrlocation.m用于绘制单幅图像误差PSNR分布图。(On the 400 block with a gray image compression method of PCA, to communicate only the main elements and characteristics of transfer vectors. Which, pcaxiefangcha.m for image compression, imresume.m parts of the image for image restoration and display, chaweight.m characteristic value for the draw weight- the main element number diagram, crdraw.m used to draw the compression ratio- the primary element number diagram, psnrdraw.m used to draw the total number of errors PSNR-principal component diagram, psnrlocation.m PSNR used to draw a single image error distribution.)

The simulator GUI is started with command ui_start in Matlab command window. WLAN simulation starts by clicking the Start Simulation button in the GUI window. WLAN simulation can be terminated, before set number of packets have been reached by pressing control-C .

说明：  代码主要实现超分辨率图像恢复，采用图形界面，可自主选择要处理的图像(Code key to achieve super-resolution image restoration, using a graphical interface, could choose to deal with image)

abaqus 重力大坝应力分析 inp 命令流文件(gravity dam stress analysis abaqus inp command stream file)

说明：  该程序用BASE-10遗传算法模拟简单函数的优化。首先，我们概述了遗传算法的一些背景信息，并定义了一些术语。接下来，我们将解释如何将该程序用于您自己的目的，并作为一个示例演示如何解决优化问题。(This program simulates the optimzation of a simple function with a base-10 genetic algorithm. First, we outline some background information on GAs and define some terminology. Following this, we explain how to use the program for your own purposes and as an example we show how to solve an optimization problem.)

说明：  LU三角分解法求解线性方程组，包含上下三角矩阵型方程组求解程序和LU分解法程序(Lu triangular decomposition method is used to solve linear equations, including upper and lower triangular matrix equations and LU decomposition method)

小波插值与小波构造的程序，包括3个程序，有均值插值和细分插值(Wavelet interpolation and wavelet construction procedures, including three procedures, have the mean interpolation and interpolation subdivision)
