Simulata VBlast Pluto code on Matlab

说明：  数字信号处理，书籍源代码。实现一些最基础的功能。适合于初学者。(Digital signal processing, books, source code. To achieve some of the most basic functions. Suitable for beginners.)

包含霍夫曼编码，算数编码，LZ编码以及GUI界面(Include Huffman coding, arithmetic coding, LZ coding and GUI interface)

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.)

使用matlab计算pid系数的程序，文档包含了程序的说明和pid的一些理论。(Pid coefficient calculated using the matlab program, the document includes a description of the procedures and some of the theories pid.)

一本介绍matlabGUI图形界面编程的书，从入门到精通，内容详细。(1 Introduction matlabGUI graphical interface programming book, from entry to the master and detailed.)

很精准的潮流计算，适合100节点内的的潮流计算(power flow)

给一段1s声音，添加入噪声，输出，然后去除噪声，输出(add noise to a 1s-length voice,excute it ,and remove the noise,and excute it)

移频法实现啸叫抑制，通过对回声信号做移频，使得回声信号加上输入信号不会再某一频点能量过大产生啸叫(Frequency shift method to achieve howling suppression, echo signals by frequency shift do so echo signal plus input signal will no longer produce a certain frequency can be excessive howling)
