实现矩阵的四则运算，并能计算矩阵的特征值和特征向量(Four arithmetic operations of matrices are realized, and eigenvalues and eigenvectors of matrices can be calculated.)

excel编制的轴承计算程序，已经在生产设计中应用过(procedures for the preparation of the bearing calculation excel)

计算机流体理论方面的文献，动网格的划分和计算(Literature, of the theory of computational fluid dynamic division and calculation of the grid)

打靶法求微分方程边值问题，这是数学上的求取方程问题的边值的方法 (Shooting method for boundary value problems for differential equations, which is to strike a mathematical equation of the boundary value problem approach)

使用matlab编写的时域有限差分法，pec边界的光子晶体。(Written using matlab finite difference time domain method, pec boundary of the photonic crystal.)

工程领域，PR方程代码.用于计算混合工质性质。(PR equation code)

based classification (SRC) has been widely used for face recognition (FR). SRC first codes a testing sample as a sparse linear combination of all the training samples, and then classifies the testing sample by evaluating which class leads to the minimum representation error. While the importance of sparsity is much emphasized in SRC and many related works, the use of collaborative representation (CR) in SRC is ignored by most literature.

有限元法计算程序，运用三角单元，进行线性插值，处理平面问题。(finite element method)

利用表达式求解和栈的只是，设计一个简易的数学题库， 可供小学生作业，并能给出分数。 要求：建立试题库文件，随机产生 n 个题目；题目涉及加减乘除，带括弧的混合运算；随时可以退出；保留历史分数，能回顾历史，给出与历史分数比较后的评价。(Use solving expressions and stack just design a simple math exam, students for the job, and can give a score. Requirements: Create test file, randomly generating n topics topics involving addition, subtraction with parentheses mixing operation ready to quit keep historical scores, can look back at history, and history is given uation scores after comparison.)

说明：  集合卡尔曼滤波(EnKF) 数据同化方法可以避免了EKF 中协方差演变方程预报过程中出现的计算不准确和关于协方差矩阵的大量数据的存储问题,最主要的是可以有效的控制估计误差方差的增长,改善预报的效果。(Ensemble Kalman Filter (EnKF) data assimilation methods can be avoided in the EKF covariance forecasting the evolution equation arising in the course of the calculation is not accurate and on the covariance matrix of a large amount of data storage problems, the most important and effective control can be estimated error variance of the growth, improvement in forecasting results.)
