Successive (Multivariate) Jump and Mode Decomposition (S(M)JMD) is the successive extension of (Multivariate) Jump Plus AM-FM Mode Decomposition ((M)JMD), a method to successively decomposing nonstationary (multi/single channel) signals into amplitude- and frequency-modulated (AMFM) oscillations and jump components. Unlike existing JMD and MJMD methods, S(M)JMD employ a successive optimization-based scheme that jointly handle AM-FM oscillations and jump discontinuities without the need to predefine K. This code is compatible with both the single channel and multichannel signals.
