灰色ＰＩＤ控制matlab仿真程序：主要包括连续、离散系统(gray PID control Matlab simulation program : including continuous, discrete systems)

1,2，3维有限时域差分用于计算电磁学matlab代码！(1,2,3 Dimension Finite Difference Time Domian for EM)

shearlet工具箱。里面有基于剪切波的图像去噪算法，实验结果表叫，它较原有算法更好地实现去除噪声与保护图像细节之间的平衡(Threshold-based shearlet image denoising algorithm, called the results table, it better than the original algorithm to remove noise and to achieve a balance between preserving image details.)

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.)

2009年出版的一本讲述matlab在工程计算方面的书，很是基础的，适合工程类专业的人员参考！(Published in 2009 on an engineering calculation in matlab books, it is based, suitable for engineering professional reference!)

属于贪婪算法中正交匹配追踪算法，用于信道估计预编码中，利用稀疏性，减小信道估计和反馈的开销，此算法的输出为所需要的系数矩阵，压缩包中还有一些说明(Belonging greedy algorithm orthogonal matching pursuit algorithm, used for channel estimation pre-encoding, the use of sparsity, channel estimation and feedback to reduce the overhead, the output of this algorithm is required for the coefficient matrix, the compressed package and some instructions)
