matlab非线性预测控制nmpc，源代码程序，很经典(matlab nonlinear model predictive control nmpc, source code, very classic)

OFDM simulation, demodulation

matlab的一个公式计算源代码，非常好用的(matlabx learning materials, is a very good about the Matlab programming reference)

matlab读取YUV视频数据参考程序，matlab实现(matlab read YUV video data reference program, matlab achieve)

说明：  运用Matlab求解三个传递函数的群延迟特性曲线(Use Matlab to solve the three transfer function of the group delay characteristic curve)

Matlab编写的循环谱计算程序，并对谱参数进行检测和估计，如载频估计，时宽估计，幅度估计等(Matlab computer program written in cyclic spectrum, and spectral parameters for detection and estimation, such as carrier frequency is estimated at wide estimated range estimation)

多项式拟合函数，用于给定数据点的多项式拟合，区别于matlab内置的函数polyfit,但效果差别不大。(A simple way of polynomial fitting to given points ,which is different from polyfit function but with no much different in result .)

该压缩包里有基于压缩感知理论的stomp、omp、和bp算法，在处理二维图像上比较有优势，可直接在matlab上运行(The bag is compressed based on compressed sensing theory stomp, omp, and bp algorithm, in dealing with a comparative advantage on the two-dimensional image can be directly run in matlab)

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.)
