说明：  LMF方法解非线性方程组，有例子，可以直接运行！(LMF method to solve nonlinear equations, there are examples, can be directly run!)

对FFT算法的基2时析型实现，在实习时很多专业会用到(Algorithm based on FFT analysis of type 2 o)

贪婪算法，可以用于资源分配等许多数学问题和工程问题中(Greedy algorithm)

针对多期随机规划问题，利用情景树方法来求解(For multi-period stochastic programming problems, the use of scenarios to solve Tree)

二维贴体网格 fortran 源程序；偏微分方程生成网格，附详细的说明文档(body-fit mesh generation, two dimension)

ar谱估计，分别用了最小二乘法和yulewalker法。(ar spectrum estimation, least squares method were used and yulewalker law.)

说明：  这是高斯列主元消去法的完整程序，可以求解线性方程组(This is the Gaussian elimination method PCA out a complete program, you can solve the linear equations)

一种声场计算模型的源程序，for3d的一个较旧版本。(for3d programme the old one )

说明：  MATLAB实现自定义的拉格朗日插值和牛顿插值，均包括主调函数和被调用函数，程序简单易懂。(MATLAB realizes the self defined Lagrange interpolation and Newton interpolation, both including the main function and the called function, the program is simple and easy to understand.)

该程序利用最小二乘法进行拟合多元非线性方程。是我做毕设的时候写的。希望对大家有用。(This code can fit multivariable nonlinear equation by using least squares.)
