对于给定某一线性时不变网络（不含受控源），根据网络属性及结构，通过编程实现自动生成其关联矩阵A和一个树。(Given a linear time-invariant network (excluding controlled source), according to the network properties and structure of the automatically generated by programming its associated matrix A and a tree.)

用matlab仿真，通过不同的方法计算矩阵的SVD分解，并用SVD的方法计算最小二乘问题和进行图像压缩(Matlab simulation, different ways to calculate the matrix SVD decomposition and the SVD method to calculate the least squares problem and the image compression)

说明：  朴素贝叶斯算法，以函数形式实现，花了一个上午的时间(Naive Bayes algorithm, in order to function the form of implementation, a morning flower time)

一维 问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度 两步差分格式进行数值求解。(Use MacCormack difference scheme for solving a two-dimensional shock tube problem)

凸轮的程序，很好，可以随更改，可以随便变化凸轮的结构。(Cam program, well, you can with the changes, you can easily change the structure of the cam.)

薄膜生长蒙特卡洛方法的，适合各种原子的啊啊啊啊啊啊啊(The Monte Carlo method of film growth is suitable for various atoms)

完成前台阶问题的计算，利用的AUSMPW格式，算法结构较为简单，所以文字说明较少(Completed on the front steps of the calculation, use of AUSMPW format, the algorithm structure is relatively simple, so less text)

试试你的运气。随机输入0到9之间的四个数，看看你能得到多少公牛，多少母牛，嘿嘿。(Try your luck. Random input between 0 to 9 the number of four to see how much bull you can get, how many cows, hehe.)

有限元法边界元法求解二维散射问题，非常有用(Finite element method for solving two-dimensional boundary element method scattering problem, very useful)
