Fortran和MATLAB的混合编程在水轮机特性曲线处理中的应用

Application of Fortran and MATLAB mixed-language programming to processing characteristic curves of hydraulic turbines

利用传统的Fortran语言编程与MATLAB强大的数学库相结合 ,阐述了使用Fortran语言对MATLAB的内蕴函数进行调用的基本方法 .并结合某具体工程实例 ,比较了MATLAB工具箱中三次样条插值函数和一般多项式插值函数对水轮机特性曲线插值结果的影响 。

Combining traditional Fortran language with the strong mathematical LIB of MATLAB, the authors expatiated on the basic principles of using intrinsic functions of MATLAB by Fortran language. And taking one project as an example, the authors research the different outcomes of interpolating characteristic curves of hydraulic turbines by using the cubic spline functions in the toolbox of MATLAB and the ordinary polynomial interpolation functions respectively. Finally, the original conclusion that the result of using cubic spline interpolation is better than polynomial interpolation, is got.
