| Abstract: | The basic principle and the realization of the maximum entropy spectral analysis in MATLAB is introduced briefly.It is showed by an example that the maximum entropy spectral analysis possesses a more high resolution than classical methods,so that the maximum entropy spectral analysis is more appropriate for the short-length data series.It is convenient for spectral analysis with MATLAB. |
