Some ATFX support has been extended, for instance to better support order spectra and order cuts exported by HEAD Acoustics, as well as basic exports from Bruel&Kjaer. Strip plots have been improved for order cut datasets.Note that the default spectral averaging has now been changed to Abs.Mean, to result in the same graphs as before. Mean is now calculated from the complex spectra, whereas Abs.Mean draws it from the absolute magnitudes. When plotting spectra, averaging has been slightly adjusted.This results in spectra which have Principal Components (PCs) as columns, instead of the time blocks of the original data. Principal components are then built from the left singular vectors and their associated singular values. When selected, a Singular Value Decomposition will be calculated from any of the two spectra. before the matrix inversion), or on the resulting characterized Blocked Forces (after the matrix inversion). This can be applied on either the indicator response spectra (i.e. The in-situ analysis now has the ability to perform a Principal Component Analysis (PCA).
