Jinping Wang · Computer Technology and Development · 2008
In the research of ocean wave,to find the power spectrum is a very important content;the interface of VB and Matlab offers a pivotal condition for writing an application that integrate efficient compute engine and humanism user' interface.For the realization of the frequency spectrum and power spectrum of random signals,one common method of estimating random signals'spectrum is FFT.In order to get the power spectrum of random signals expediently and fleetly,introduces a method to implement FFT,which is based on interface of VB and Matlab.The software for estimating spectrum of waves is developed based on this method.The software has been successfully applied to the waves of data processing.Practice has proved that:The method is universal,so it could also be used for other random signals' spectrum estimation.
