这是一个滤波器，用来将时域信号转换位频域进行分析滤波后，再转为时域信号的小程序(This is a filter for converting the digital time domain signal analysis of the frequency domain filtering, a time domain signal of the small sub-program)

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.)

ROI area identification, iteration, MCAA, zbthresh This program is simple, everyone can learn under

本程序利用matlab实现3维栅格地图建模，调试成功，有兴趣的可以下载(This procedure using matlab to achieve a three-dimensional grid map modeling, debugging success, interested can download)

LTP是LBP的改进，可以更好的提取纹理特征(The LTP is more efficent than LBP)

基于BP网络的曲面拟合，和BP网络仿真程序(BPnet)

此文件是matlab程序，处理指纹图像，采集特征点最终实现指纹识别！(This file is the matlab program, processing fingerprint images, collection of feature points ultimately fingerprint!)
