Webhs = hht(imf,fs) returns the Hilbert spectrum hs of the signal specified by intrinsic mode functions imf, and the optional sampling frequency fs. hs is useful for analyzing signals that comprise a mixture of signals whose spectral content changes in time. Use hht to perform Hilbert spectral analysis on signals to identify localized features. WebJul 2, 2024 · I can implement eemd and hht on my signal data to obtain imf and hilbert spectrum with matlab2024a. However, i don't kown how to get hilbert marginal spectrum. I had found some codes, but they are not suitable for my matlab version I think. The codes I found contain "hhspectrum" and "toimage" which the matlab2024a cannot recognize.
