Illustration of DMD triple for one normal and one abnormal gait. a All the amplitudes \(a_j\) in a descending order. b The \(L^{\infty }\) norm for each mode vector \(\phi _j\). c All the norms of spectra \(s_j\) while d The spectra in the complex plane. Note that the real parts of the spectra for both normal and abnormal gaits are close to zero. We remark here that modes and spectra are reordered according to amplitudes. Note that complex values of DMD triple may occur in the numerical calculation, norm of complex values are used in the plots.
