GM-with-Markov

灰色预测GM（1，N）代码，用于数学建模，提供残差等(Gray forecast GM (1, N) code for mathematical modeling residuals)

在时间序列分析中自动完成数据的导入、分析与导出(In time series analysis is done automatically import data, analysis and export)

股票数据爬虫，matlab版本，与网上同一类型的区别在于，能够直接运行，有一定的借鉴意义。(Stock data crawler, matlab version, with the same type of difference between online, can run directly, have certain reference significance.)

MCMC方法主要是为了解决有些baysian推断中参数期望E(f(v)|D)不能直接计算得到的问题的。 其中v是要估计的参数，D是数据观察值(The concept consists of two parts:markov chain and monte carlo integration。)

维纳滤波器（Wiener filter）是由数学家维纳（Rorbert Wiener）提出的一种以最小平方为最优准则的线性滤波器。在一定的约束条件下，其输出与一给定函数（通常称为期望输出）的差的平方达到最小，通过数学运算最终可变为一个托布利兹方程的求解问题。维纳滤波器又被称为最小二乘滤波器或最小平方滤波器，目前是基本的滤波方法之一。(Wiener filter (Wiener filter) is caused by a mathematician Wiener (Rorbert Wiener) proposed guidelines for the minimum square optimal linear filter. Under certain constraints, which outputs a given function (often called the desired output) reaches the minimum squared differential, the final mathematical operation may become a problem solving Equation Leeds Taub. Wiener filter is also known as the least squares filter or least squares filter, currently one of the basic filtering methods.)

本书介绍了光学设计的理论和并给出了一些实例及相关的参考文献，对于从事镜头设计的研究者来说具有很好的参考价值。(This book introduces the theory and optical design and gives some examples and related references for researchers engaged in the lens design is a good reference value.)

说明：  该程序计算Kretschmann和Otto结构的反射率。(Reflectivity of Kretschmann and Otto structure.It can be determined the SPR angle)

自己做的三相整流器，使用矢量控制。simulink的仿真平台做的，很强大哦(this is a three phase rectifier)
