class CONNECTIVITYLIB::Coherency

Shared core of the coherence / imaginary-coherence family.

compute fills the per-trial DPSS spectra and accumulates the cross- and auto-spectral sums in ConnectivitySettings::IntermediateSumData. The two public reductions then collapse the complex coherency to a real scalar per channel pair: calculateAbs returns |Coh_{xy}(f)|^2 (classical magnitude-squared coherence, symmetric, sensitive to zero-lag mixing) and calculateImag returns |Im(Coh_{xy}(f))|, the volume-conduction-robust imaginary coherence of Nolte et al. (2004).

Complex coherency core; produces magnitude-squared and imaginary-part reductions for downstream metrics.
