pyriemann.geometry.mean.mean_euclid(X, sample_weight=None, **kwargs)[source]¶

Mean of matrices according to the Euclidean metric.

Euclidean mean is also called arithmetic:

\[\mathbf{M} = \sum_i w_i \ \mathbf{X}_i\]

with \(w\) being the weights which sum to 1.

Parameters:

Xndarray, shape (…, n_matrices, n, m): Set of matrices.
sample_weightNone | ndarray, shape (n_matrices,), default=None: Weights for each matrix. If None, it uses equal weights.

Returns:
