How can I perform Variational Mode Decomposition (VMD) with MATLAB?

VMD decomposes a real signal into a number of narrowband mode functions whose envelopes and instantaneous frequencies vary much more slowly than their central frequencies. The algorithm determines all mode waveforms and central frequencies simultaneously and thus distributes errors among them in a balanced way. Variational mode decomposition is suitable for the study of nonstationary or nonlinear signals.

The "vmd" function was added to MATLAB in R2020a:

• https://www.mathworks.com/help/wavelet/ref/vmd.html

This function requires either Signal Processing Toolbox or Wavelet Toolbox.

In R2022a, VMD support was also added to the handy "Signal Multiresolution Analyzer" App that comes with Wavelet Toolbox:
