替代数据方法（基于相位随机化方法），检验续写的非线性(Surrogate data method (based on random-phase method), non-linear write test)

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)

说明：  FFT，整型数据代替浮点型数据 本程序是搜集资料并加上自己的分析，整了很长时间才测试通过的FFT程序，运行时间和所占内存方面都比较满意。(FFT, integer data instead of floating point data This program is to collect data and add their own analysis, the FFT program passed the test for a long time, the running time and memory occupied are relatively satisfactory.)

nsolgm 算法 是求解非线性方程组的一种非常有效而且又快捷的方法(nsolgm algorithm for solving nonlinear equations is a very effective and efficient way and)

很详细的一维FDTD介绍，以及MATLAB程序说明(Very detailed one-dimensional FDTD presentation and description of the MATLAB program)

非线性方程数值解法的数学基础，有牛顿法，割线法等(Mathematical foundations of numerical solution of nonlinear equations, Newton method, secant method)

指派问题的匈牙利解法，从文件中读入待指派的数据。(Assignment problem of the Hungarian method, read from a file to be assigned to data.)

说明：  udf模拟油膜蒸发过程及其温度分布和各组分的浓度(Udf simulates oil film evaporation process and its temperature distribution and concentration of each component)

二维泊松方程的定解问题：用5点菱形异步迭代格式求解泊松方程，h=5/4 ,误差s=1e-6 (Differential method for Poisson equation)
