改进了跨声速偶极子网格法（TDLM），且在颤振计算中能自动求颤振点速度，从而较大地提高了计算速度，并有利于方法在较大马赫数及较大减缩频率时的应用。(Dipole source grid method)

用谱方法计算流体力学一些流动现象的整体稳定性,利用自然梯度算法，包括四元数的各种计算。( Spectral methods of computational fluid dynamics flow of some of the overall stability of the phenomenon, Use of natural gradient algorithm, Including quaternion various calculations.)

计算各种气象物理量，包括散度、涡度、螺旋度、垂直速度、水汽通量、比湿、假相当位温、k指数等的grads 程序，(Calculate various meteorological physical quantity, including divergence, vorticity, helicity, vertical velocity, water vapor flux, specific humidity, pseudo-equivalent temperature, k index grads program,)

很详细的一维FDTD介绍，以及MATLAB程序说明(Very detailed one-dimensional FDTD presentation and description of the MATLAB program)

本程序是基于非等距节点的正交多项式的最小二乘法拟合算法，该算法已经在vc++6.0下调试通过，经多次验证，本算法的拟合误差较小。(This procedure is based on equidistant nodes of non-orthogonal polynomial least squares fit algorithm, which has been in vc++6.0 through debugging, after repeated verification, the algorithm of fitting error is small.)

用MATLAB实现单因素/两因素重复测量方差分析，自带工具包中只有非重复测量的方差分析函数ANOVA。anova_rm实现单因素；rm_anova2实现两因素( function stats = rm_anova2(Y,S,F1,F2,FACTNAMES) Two-factor, within-subject repeated measures ANOVA.For designs with two within-subject factors. function [p, table] = anova_rm(X, displayopt)Single factor, repeated measures ANOVA.)
