自己总结的一些现阶段用得比较多的尾流计算模型(Some of your summary of present with more drafting calculation model)

这是地球物理学中声波波动方程正演程序，非常有用(this is a program about finite difference)

关于一的微分方程数值解,一维波动方程初边值问题Crank-Nicholson格式,及追赶法(On one of the numerical solution of differential equations, one-dimensional wave equation Crank-Nicholson format, and to catch up with the Law)

实现复数运算符的重载，对C++初学者来说有一定的参考价值。(Complex operator overloading, C++ beginners a certain reference value . )

本代码为《最优化理论与方法》书籍重的信赖域算法的代码，本代码中的目标函数和约束等初值可由需要进行改变，来得到所期望的计算(The code for the " optimization theory and method" heavy books trust region algorithm code, the code of the objective function and constraints may need to change the initial value to get the desired calculation)

根据海水的速度 密度 温度 盐度等计算海洋各处的压力数值(Speed ​ ​ according to the density of seawater temperature and salinity values ​ ​ calculated pressure throughout the ocean)

说明：  此代码包括牛顿法和梯度下降法的实现过程，最优化以及算法中常见的问题解决方式(This code includes the process of Newton method and gradient descent method)

计算力学基础，中国科技大学精品教材，王秀喜，吴恒安编著(The basis of Computational Mechanics, University of Science and Technology of China, boutique textbook series)

说明：  Umat Abaqus for plasticity

说明：  牛顿法又称牛顿-拉弗森方法（Newton-Raphson method），是一种在实数域和复数域上近似求解方程的方法。本程序收敛速度快，迭代步数可取大一些(Newton method, also known as Newton-Raphson method, is an approximate method for solving equations in real and complex fields. The program has fast convergence speed so the number of iteration steps can be larger.)
