划分网格一个开源的库，有限元的算法，很好用(Meshing an open source library = for finite element)

说明：  这是一个ACM试题中的算法，叫分而治之算法，上面有PPT还有实例代码，希望喜欢ACM的同学可以喜欢(This is a Question in the ACM algorithm, called divide and conquer algorithms, there are examples of the code above, there are PPT hope that students like to be like the ACM)

说明：  用C语言编写多元线性回归方程，写得不好的地方请指教！(Using C language multiple linear regression equation, where poorly written, please advice!)

C++编写“三维粱单元有限元计算内核”，对杆系有限元的理论和C++的理解有了很大提高(C++ written " three-dimensional beam finite element kernel module" , and on finite element theory and the understanding of C++ has been greatly improved)

包括牛顿法，阻尼牛顿法，变尺度算法，最速下降法的优化算法程序。(Newton' s method, damped Newton method, variable metric algorithm, the steepest descent method optimization algorithm.)

2维的FDTD C程序(2-dimensional FDTD C procedures)

矩阵转换问题 行与列的个数均为n 的矩阵称为n 阶方阵。假定矩阵中的每个元素的值在0到9之间，则可以将矩阵中的所有元素按行依次排列得到一个“单行矩阵字符串”。(Matrix conversion, the number of rows and columns of the matrix n are called n-order square. Assume that each element of matrix value in the 0 to 9, you can press all the elements of the matrix rows in order of priority for a " single matrix string." )

用谱方法计算流体力学一些流动现象的整体稳定性,MIMO OFDM matlab仿真,本程序的性能已经超过其他算法。( Spectral methods of computational fluid dynamics flow of some of the overall stability of the phenomenon, MIMO OFDM matlab simulation, This program has exceeded the performance of other algorithms.)

在Z2[X]中判断一个多项式是否本原多项式，并能对给定的多项式求逆。 (in Z2 [X] to judge whether a polynomial primitive polynomial, and the right to the inverse polynomials.)

实现卡尔曼滤波算法，可以进行参数估计、插值、滤波和预报(The Kalman filter algorithm, parameter estimation, interpolation, filtering and prediction)
