Analysis and application of hybrid programming for Matlab and V C++ based on Matcom

To monitor the dynamic balance of rotor online,the first-harmonic related with signal of vibration is required to calculate.The interactive programming for Matlab and Visual C++ completing FFT algorithm,can unite their advantages to achieved all goals.After discusses the 3 kinds of methods that use the Matlab in Visual C++ environment,emphasizes to introduce the step of mixied programming with Matcom,handles for the development the applied procedure of the data of large quantity provided the basis.The results show that the hybrid programming using Matcom speeds up the development of application programm,improve the programming efficiency,and this technique can widely applied in many aspects.
