match_reference

hypercoil.neuro.synth.match_reference(signal: Tensor, reference: Tensor, use_mean: bool = False) → Tensor

Match both the spectrum and covariance of a reference signal.

Dimension:

signal : \((D, N)\)

D denotes dimension of the multivariate signal and N denotes the number of observations per channel.

reference : \((D, N)\)

As above.

Parameters:

signaltensor

Input signal.

referencetensor

Reference signal.

use_meanbool (default False)

Indicates that, instead of matching the spectrum of the corresponding channel in the reference signal, all channels are matched to the mean spectrum across all reference channels.
