Friends of the recent research and a reference to communicate Matlab time-frequency analysis, that Matlab does not provide a direct rendering of time- frequency distribution of command, but in time- Scalogram instead. But often we spend time- frequency diagram to analyze the signal, these two days focus on relevant information collected, of which the Fileexchange in MathWorks.com Center Matlab to find a good time-frequency analysis tool, the use of Matlab GUI interface development, which the preparation of nuclear use C, I feel easy to use, fast analysis and mapping, and expression has a variety of graphics options.
