在计算流体力学中，多项流中有相变时，基于温度的相变UDF(Mass based on the temperature of the phase change in the UDF)

薄板样条，一种很好的拟合曲线的方法。是最近比较常用的拟合方法。(thin plate spline is so nice fitting method. Features: (1) support arbitrary control points (2) allow regularization (3) estimate the warp parameters from corresponding pairs )

说明：  算法知识讲解，是一本不错的算法入门级教材的pdf版本(This is a good introduction to algorithm)

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)

P-R方程编程源代码，用于热力学相平衡计算，计算泡点和露点，欢迎大家下载！(PR equation programming source code, used to calculate the thermodynamic equilibrium, the bubble point and dew point calculation, welcome to download!)

说明：  PCA主成分分析的标准MATLAB程序,可通用,非常有效(PCA principal component analysis of the standard MATLAB procedures, can be universal, very effective)

说明：  计算时程信号数据的快速傅里叶变换，进行频谱分析(The fast Fourier transform of time history signal data is calculated and the spectrum analysis is carried out)

说明：  研究舍入误差的例程，可以帮助初学计算方法的人。(Of rounding error in the routine that can help beginners who calculation.)

理想流体势流的有限元求解程序,简单易懂，适合初学者对该方法编程的一个初步认识,程序内有详细的注释(Potential flow of ideal fluid finite element solver, easy to understand, this method is suitable for beginners programming a preliminary understanding of the program with detailed notes)
