mdof

The mdof package features the following high-level functions for quickly performing system identification:

outid(outputs, dt, **options)	Fundamental periods P and modeshapes Phi identification from output array.
modes(inputs, outputs, dt, **options)	Fundamental periods P and modeshapes Phi identification from input and output arrays.
eigid(inputs, outputs, **options)	State space system eigenvalues vals and eigenvectors vecs identification from input and output arrays.
sysid(inputs, outputs, **options)	State space system realization (A, B, C, D) from input and output arrays.
predict(realization, inputs, **options)	Prediction of output from system realization (A, B, C, D) and inputs.

The following modules expose the inner building blocks for frequency domain and time domain analysis of vibration signals:

• mdof.markov module
• mdof.realize module
• mdof.modal module
• mdof.transform module
