Eigensystem Realization Algorithm

The Eigensystem Realization Algorithm

Identify mode shapes, frequencies, and damping from free-decay measurement data.

The ERA Class

ERA(resp, sr, *[, svd_tol, auto, alpha, ...])

Implements the Eigensystem Realization Algorithm (ERA).

The Natural Excitation Technique

NExT(resp, sr, *[, ref_channels, lag_start, ...])

Use NExT method to prepare measurement data for ERA
