rvmd() is a MATLAB implementation of reduced-order variational mode decomposition (RVMD).
RVMD is a multi-component extension of variational mode decomposition (VMD), which combines the low-order representation in modal analysis (for fluid dynamics). RVMD can adaptively extract low-order dynamics featured by transient or non-stationary properties in space-time data.
