Version 1.2.8
Made some significant updates to the ERA class (eigensystem realization algorithm).
- Added the output EMAC indicator (EMACO) which may be superior to the normal EMAC
- Added the related CMIO indicator
- Fix bugs
- Added more features (configurable Hankel matrix size, configurable figure labels, the verbose option)
- Simplified some coding
Also added a beta version of the Natural Excitation Technique (NExT) for preparing ambient vibration data for ERA. Implemented both the time domain and frequency domain with windowing approaches to compute cross-correlations.
