pyriemann.utils.geodesic.geodesic¶

pyriemann.utils.geodesic.geodesic(A, B, alpha, metric='riemann')[source]

Return the matrix at the position alpha on the geodesic between A and B according to the metric :

Parameters: A – the first coavriance matrix B – the second coavriance matrix alpha – the position on the geodesic metric – the metric (Default value ‘riemann’), can be : ‘riemann’ , ‘logeuclid’ , ‘euclid’ the covariance matrix on the geodesic
