g_fitting

说明：  自己编写的期望最大化（EM）算法的MATLAB实现，里面有较为运行方法和程序说明，对新手有很好的帮助( I have written the expectation-maximization (EM) algorithm in MATLAB, which has run more methods and procedures described, there is a good help for the novice)

三次样条曲线拟合代码，先训练，后差值，计算非常准确(Three times spline curve fitting, the first training, and after, computation is very accurate)

常微分方程求解的搜索延拓法，克服了Newton-Raphson法对初值问题影响过大的问题(Solving Ordinary Differential Equations search continuation method to overcome the Newton-Raphson method for initial value problem of the impact of the problem is too large)

提供几种著名的大型线性方程组迭代算法，包括CG、PCG、Lanczos、MINRES(Several well-known large-scale linear equations iterative algorithm, including CG, PCG, Lanczos, MINRES)

根据分好的单元，进行有限元分析。计算每个单元中四个高斯点的应力，应变，主应力以及位移。(According to sub-good unit, finite element analysis. Calculated for each unit in the four Gauss point stress, strain, principal stresses and displacements.)

基于Python编写的用于曲线拟合，最小二乘法(Based on Python for curve fitting, least squares method.)

本程序主要根据有限元法编写，可以求解薄板的振动和静力分析问题(This procedure mainly based on the preparation of the finite element method can solve the plate vibration and static analysis of the problem)
