WebDynamic mode decomposition (DMD) is a relatively recent mathematical innovation that can solve or approximate dynamic systems, among other things, with respect to coherent structures that grow, decay, and/or vibrate in time. The coherent structure is called DMD mode. Each DMD mode has corresponding time dynamics defined for a single eigenvalue.
