Delegates to signal::coherence when present; otherwise builds a
Welch-style estimator from morie_dsp_psd_welch and a parallel CSD.
Usage
morie_dsp_coherence(x, y, fs = 1, nperseg = 256L)
Arguments
- x
Numeric vector.
- y
Numeric vector.
- fs
Sampling frequency (Hz). Default 1.
- nperseg
Segment length. Default 256.
Value
List with freqs and coh (magnitude squared coherence).
