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.)

在matlab中生成单边指数调幅信号． y=amexpols(N,t0)Ｎ生成信号的点数，t0函数的起始点，y返回信号．(generated in Matlab unilateral index AM signal. Y = amexpols (N, t0)- N signal points, the starting point t0 function, y return signal.)

z源逆变器的单相最大升压控制，可以更进一步的改善直流侧电压值，相对于简单升压控制可以减小直流电压的输入值。(Z source inverter single-phase biggest boost control, can further improve the dc side voltage value, compared with the simple boost control can reduce the input value of the dc voltage. )

MATLAB5.X应用与技巧也是一本比较老的关于MATLAB的教材，虽然是比较老版本的，但也有很好的指导做用(MATLAB5.X applications and skills is a relatively old on MATLAB materials, although the old version, but there are also a good guide to do with)
