说明：  CZT和FFT的C语言实现代码，能有效滤除谐波，噪声。获得信号的频率，是一种良好的频率测量算法。(CZT and FFT of the C language code, can effectively filter out harmonics and noise. Access to the signal frequency, is a good algorithm for frequency measurement.)

牛顿插值法进行多项式逼近，matlab编译成功，直接可用(Newton interpolation polynomial approximation method, matlab compiled successfully, directly available)

计算流体力学软件FLUENT计算空气龄的udf文件(FLUENT CFD software udf file to calculate the air age )

PLIC程序现今VOF中应用较多的方法，精度较高。(PLIC VOF process the application of more modern methods and high precision.)

说明：  神经网络算法，希望能对大家有点点帮助，可以相互交流(Neural network algorithm, I hope everyone can have little bit of help, they communicate with each other)

FLUENT中离散相粒子追踪设置及相关计算，设计用户自定义相关内容(Discrete phase particle tracking in FLUENT)

说明：  可用于层次分析法比较评价，主函数输入初始矩阵，调用层次分析函数(It can be used for comparative evaluation of analytic hierarchy process. The main function input the initial matrix and call the analytic hierarchy process function.)

用C++编的一些最优化作业中的程序,有Newton法,DFP法,共轭梯度法,单纯形法,内点法,外点法,内外点法,都能使用,我已经全部调试过了(C compile some of the most optimized operating procedures, Newton, DFP, conjugate gradient method, the simplex method, interior point method, the points outside the law, outside point method can use, I have all over Debugging)

重力频率域位场延拓。将观测面的位场数据（a20_mag.gtd）向上延拓3.3m，之后与已知的理论值（a53_mag.grd）进行比较，计算其均方误差；反之，将观测面的位场数据（a53_mag.grd）向下延拓3.3m，之后与已知的理论值（a20_mag.grd）进行比较，计算其均方误差。(gravity frequency field extend)

PETSc (Portable, Extensible Toolkit for Scientific Computation) 是美国能源部ODE2000 支持开发的20 多个ACTS 工具箱之一，由Argonne 国家实验室开发的可移植可扩展科学计算工具箱，主要用于在分布式存储环境高效求解偏微分方程组及相关问题。(PETSc (Portable, Extensible Toolkit for Scientific Computation) is ODE2000 U.S. Department of Energy to support the development of one of more than 20 ACTS Toolkit, developed by the Argonne National Laboratory' s Portable, Extensible Toolkit scientific computing, mainly used in the distributed memory efficient environment for solving partial differential equations and related issues.)
