pyriemann.utils.tangentspace.tangent_space(covmats, Cref)[source]¶

Project a set of covariance matrices in the tangent space according to the given reference point Cref

Parameters:	covmats – Covariance matrices set, Ntrials X Nchannels X Nchannels Cref – The reference covariance matrix
Returns:	the Tangent space , a matrix of Ntrials X (Nchannels*(Nchannels+1)/2)
