WebDynamic mode decomposition is a data-driven method that can produce a linear reduced order model of a complex nonlinear dynamics such that the temporal and spatial modes of the system are obtained. This method was first introduced by Schmid [40] in the field of fluid dynamics. The increasing success of DMD stems from the fact that it is an ...
