说明： 基于经验模态分解的时频分析代码，对研究时间序列极为有用，亲测可用
(Time frequency analysis code based on empirical mode decomposition is very useful for studying time series, and pro test is available)

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.
