%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. For more
details see Mallat and Zhang (1993) <doi:10.1109/78.258082>, Pati et al.
