通过matlab计算allan variance，较为复杂，注释详细(Matlab Allan variance, more complex, detailed notes)

时间积分算法在有限元动力学中的应用，可以计算结构的瞬态响应(This class implements a Newmark beta-gamma predictor-corrector time inte- gration scheme, with accelerations as primary unknowns. .A Newmark scheme assigns to the dofs the following 5 unknowns : - the displacement d and its predictor D - the velocity v and its predictor V - the acceletion a . Their expressions are calculated by the dofs in class Dof.)

说明：  独立分析 主成分分析 可以提取矩阵独立成分与主成分，显示空间特征与时间特征以及对应的奇异分析用于计算能进行奇异值分解等。主要用于数值的提取计算等。(It can extract the independent and principal components of matrix, display the spatial and temporal characteristics, and use the corresponding singular analysis to calculate the singular value decomposition. It is mainly used for extraction and calculation of numerical value.)
