特征线法（中矩形公式）数值模拟一维不可压缩瞬变流动(Characteristic line method (in the rectangle formula) one-dimensional numerical simulation of transient flow of incompressible)

HHT MATLAB CODE HHT是一個客觀而有自適性(adaptive)的數據分析方法。它利用物理空間的尺度為基準分解複雜數據，因此各分量皆有豐富的物理意義。由於它有自適的特性，它可以適用於分析非線性，非穩定性過程所產生的數據。經過近數年來的廣泛研究與應用，HHT已被認定為是一個有革命性又有效的方法。(HHT MATLAB CODE)

基于simulink 的OFDM框架仿真文件系统仿真(Simulink simulation based on the OFDM framework for file system simulation)

This is a one of the data mining algorithm completly made by me. This is based on feature subset selection. One of the popular algorithm of feature selection named Fast Correlation based feature selection algorithm(FCBF).It s complete code is here with other function files used in it. I can provide you with more description of it if needed.

说明：  数字图像修复算法的评价标准也是从两个方面进行评价的，一个是修 复算法的效率，一个是修复后图像质量。修复算法的效率主要就是看修复 图像所用的时间，可以用时间就行量化。而图像质量很难从量上唯一的进 行评价，目前图像修复质量还没有统一的评价标准，从实际应用出发，修 复后图像质量的好坏大多数是从以下两个方面就行评价，修复后图像给人 主观上的“满意度”和客观上图像的cnr、enl、epi、psnr、snr来评判。(The evaluation criteria of digital image restoration algorithms are also evaluated from two aspects, one is repair. One of the efficiency of complex algorithm is the image quality after restoration. The efficiency of the repair algorithm depends mainly on the repair. The time spent on the image can be quantified in terms of time. But image quality is difficult to improve quantitatively only. At present, there is no uniform evaluation criterion for image restoration quality. Starting from practical application, repair The quality of restored images is mostly evaluated from the following two aspects, and the restored images are given to people. Subjective "satisfaction" and objective image cnr, enl, epi, psnr, SNR to judge.)

it is for electrical engineering in power systerm. it is a matlab function for pv-power load.
