Multivariate event-related coherence

Computes event-related power and coherence in multivariate signals

Function estimates several time-frequency measures using Fourier decomposition of data matrix x, including power-spectral density, inter-trial coherence and coherence between signals. Time-frequency measures are computed relative to temporal events and aggregated across these trials. All measures are derived from the cross- and autospectra estimated using Welch's periodogram method.
