Conventional dynamic eigenanalysis is well-known to structural engineers -- from system properties and a given excitation, the goal is to determine the system's dynamic response.

output_motion = eigen(M,C,K, input_motion)

The mdof system id package allows structural engineers to solve inverse eigenanalysis and related problems -- from structural vibrations, the goal is to identify the system properties.

Inverse eigenanalysis:

eigvecs, eigvals = eigid(input_motion, output_motion)

State space system identification:

A,B,C,D = sysid(input_motion, output_motion)

Create beautiful visuals for historical modal property documentation with integration of the osmg and opensees packages.
