matcorr

matcorr(first, second, remove_mean=False, method=2, weighting=None)

Match rows of two matrices by absolute cosine correlation.

Methods are 0 (globally optimal Hungarian assignment), 1 (Vogel approximation), and 2 (successive maximum correlation). Returned row indices are 1-based. Rectangular inputs return min(rows) unique pairs. EEGLAB forces method 2 unless both matrices are square.

Parameters:

• first (Any)

• second (Any)

• remove_mean (bool)

• method (int)

• weighting (Any | None)

Return type:

tuple[ndarray, ndarray, ndarray, ndarray]
