mapcorr

mapcorr(first, second, first_channels, second_channels, remove_mean=False, method=2, weighting=None)

Match rows after aligning map columns by common channel labels.

Returned row indices are 1-based. Subtract 1 before using them as NumPy indices. EEGLAB forces method 2 for some non-square maps; the requested method is kept here.

Parameters:

• first (Any)

• second (Any)

• first_channels (Sequence[Mapping[str, Any]])

• second_channels (Sequence[Mapping[str, Any]])

• remove_mean (bool)

• method (int)

• weighting (Any | None)

Return type:

tuple[ndarray, ndarray, ndarray, ndarray]
