On dynamic mode decomposition: Theory and applications

WebConnecting Dynamic Mode Decomposition and Koopman Theory Introduced in 1931, the Koopman operator is a linear operator that completely describes an autonomous nonlinear dynamical system. This is accomplished by mapping a finite-dimensional nonlinear dynamical system to an infinite-dimensional linear system. WebThe focus of this book is on the emerging method of dynamic mode decomposi-tion (DMD). DMD is a matrix decomposition technique that is highly versatile and builds upon the power of singular value decomposition (SVD). The low-rank struc-tures extracted from DMD, however, are associated with temporal features as well as correlated spatial activity. http://www.umn.edu/~mihailo/software/dmdsp/ cohousing ontario
