说明：  一维信号BP重构算法，先生成稀疏度为K的稀疏矩阵，再加入高斯白噪声进行算法重构以及质量衡量。(BP signal reconstruction algorithm for one dimensional, Mr. into sparse matrix sparsity of K, then the Gauss white noise and measure the quality of reconstruction algorithm.)

BP神经网络识别手写字符验证码，包括10721张字母、数字样本(BP neural network handwritten character recognition codes, including 10,721 letters, numbers, samples)

可以将数据集按行任意调换顺序，给出了IRIS数据集及例子。(It can do any exchange data set in order, and give the IRIS data set and examples. )

扇形传感器区域覆盖优化的虚拟力导向粒子群算法(Fan-shaped area coverage sensor-driven power optimization of the virtual particle swarm optimization)

数字滤波器的MATLAB实现,很实用，非常好，欢迎下载不用上传就能下载(FIR)

《Matlab应用大全》书本上的程序，有初级到高级，包含了信息处理，数字图像处理，模糊算法，小波变换等(Program on the books " Matlab application Daquan" There beginner to advanced, including information processing, digital image processing, fuzzy algorithms, wavelet transform)

说明：  使用个股日内髙频收益率计算己实现值进行分析,同时计算得到二阶矩 和高阶矩值并进行对比。本文根据己实现量的大小将所有样本股分为己实现值由 小到大的姐别,分别跟踪各股票组合的收益,探索预期收益与个股己实现值之间 的变化关系,然后将分组的结果应用于多空策略,为提高资产配置收益提供参考。 同时,将各己实现变量和各类对预期收益产生影响的控制变量放在一起构建 Fama-MacBeth截面回归,分析高频已实现量是否具有定价能力。(The realized value is calculated by using the daily gust rate of return of individual stocks, and the second-order moments are obtained by calculating at the same time. Comparisons are made with higher order moment values. This paper divides all sample stocks into realized values according to the size of realized stocks. Sisters from small to large track the earnings of each stock portfolio, and explore the relationship between expected earnings and the realized value of each stock. Then the grouping results are applied to the multi-empty strategy to provide reference for improving asset allocation returns.)

这是一段去噪程序，与图像修补相关但不是修补代码，有一定的参考价值(Denoising procedures)

Analysis of steady state/ transient behaviour of HVDC systems due to AC/ DC Faults, commutation failure etc. using PSCAD simulating software. Also conducted studies on control methods/ protection requirements as well as distribution on the Delhi-Rihand HVDC system.
