说明：  使用Eviews编写covar程序，实现covar的计算(Using Eviews to write Covar)

说明：  带精英决策的多目标优化关键程序，希望对大家有用。(Key procedures of multiobjective optimization with elite decision)

ABAQUS纤维增强复合材料损伤失效UMAT(ABAQUS UMAT subroutine for fiber-reinforced composite failure analysis)

有限元计算开源库，可以用于计算动力、静力、磁场等等方面的计算(Finite element calculation open source library)

滤波器与匹配电路的设计，基于简化实频技术的matlab实现(the SRFT achieves an optimal lter design byusing computer-aided optimization. This code will describe SRFT and a MATLABR implementation of the SRFT currently under development)

说明：  常用于分析降水、径流、气温等要素时间序列的趋势变化，其优点在于样本不需要遵循某一特定的分布，而且很少受到异常值的的干扰，计算简便。(It is often used to analyze the trend change of time series of factors such as precipitation, runoff and air temperature. Its advantage is that the sample does not need to follow a specific distribution, and is rarely disturbed by outliers, so it is easy to calculate.)
