Description: Provides tools for analysing and decomposing time series
        data using the Matching Pursuit (MP) algorithm, a greedy signal
        decomposition technique that represents complex signals as a
        linear combination of simpler functions (called atoms) selected
        from a redundant dictionary. Support for the Orthogonal
        Matching Pursuit (OMP) variant of the classical MP algorithm is
        also provided. For more details see Mallat and Zhang (1993)

SystemRequirements: external tool (installed via empi_install()
        function). The package uses the implementation of the Matching
        Pursuit algorithm (Enhanced Matching Pursuit Implementation;
        EMPI) by Piotr T. Różański, available at
        https://github.com/develancer/empi.
