摘　　要：利用VC++语言编程与M atlab的强大数据库相结合以及M atcom可以把M atlab的M文件转成相同功能的C++代码的功能。阐述运用VC++语言对M atlab内部函数进行调用的基本方法。研究不同数值处理方法的曲线拟合对水轮机特性曲线绘制与转换效果的影响,并提出水轮机特性曲线的插值与拟合的新方法;以此结合M atlab工具箱中三次样条插值函数和一般多项式插值函数分别进行编程,并就工程实例进行了水轮机特性曲线的转换与绘制。Combining VC ＋＋ language with the strong database of Maltab, expatiated on the basic principles of using intrinsic function of Matlab by VC ＋＋ language. The research the curve estimation by using different data process measures that has an effect on the results of drawing and transition characteristic curves of hydraulic turbines, and introduce a new way of characteris- tic curves interpolating and estimation of hydraulic turbines. In light of combining the cubic spline functions in the toolbox of Matlab and the ordinary polynomial interpolation functions, proceed on compiler respectively, and taking one project as an example, carry out drawing and transition characteristic curves of hydraulic turbines.
