log_map: Logarithmic mapping of SCMs

In LauraMasiero/RiemannR: RiemannR - EEG-based BCI analysis with Riemannian geometry

Description

This function allows to project sample covariance matrices which lies in a Riemannian manifold at the tangent space computed at a given point of the manifold.

Usage

log_map(scm_list, C)

Arguments

scm_list	a list of sample covariance matrices.
C	centroid. The point of the Riemannian manifold in which the tangent space is computed.

Value

It returns a list containing the matrices projected in the tangent space.
