Note: EMD source code can be download from http://perso.ens-lyon.fr/patrick.flandrin/emd.html. If you have any problems in running this code, please contact Heng Li via wudaomana@gmail.com. Main Files: - tvfemd.m Computes the TVF-EMD. - splinefit.m Computes the B-spline least squares approximation (B-spline order = 26). Optional Files: - INST_FREQ_local.m: This function computes the Hilbert-Huang spectrum using the Hilbert transform, the instantaneous amplitude and the instantaneous - spectrogram_emd.m transforms the 2D instantaneous amplitude and frequency into 3D spectrum matrix to plot the instantaneous amplitude contours on the time-frequency plane. - disp_hhs.m plots the 3D HHS spectrum of the spectrum matrix obtained as an output from spectrogram_emd.m.
