Description: Signals are decomposed into oscillatory modes by empirical
        mode decomposition and its ensemble, complementary ensemble,
        complete ensemble, masked, bivariate and multivariate variants,
        by variational mode decomposition and its multivariate and
        successive variants, and by local mean decomposition, iterative
        filtering, time varying filter empirical mode decomposition and
        the empirical wavelet transform; the synchrosqueezed wavelet
        transform is also provided. Empirical mode decomposition is due
        to Huang et al. (1998) <doi:10.1098/rspa.1998.0193>, its
        ensemble variant to Wu and Huang (2009)
        <doi:10.1142/S1793536909000047> and variational mode
        decomposition to Dragomiretskiy and Zosso (2014)
        <doi:10.1109/TSP.2013.2288675>. The modes can be described by
        their instantaneous amplitude and frequency and their Hilbert
        spectrum, tested as intrinsic mode functions or against white
        noise, selected by energy and compared through orthogonality,
        mode splitting, reconstruction quality, ensemble dispersion and
        similarity measures. Acceleration, velocity and displacement
        records stored as a long table of time, value, quantity and
        component are decomposed for every record and quantity in one
        call, with a warning and a regularization of the time grid when
        it is not uniform.
