Description
Computes the Riemannian distance using the Fisher (affine-invariant) metric between two Symmetric Positive Definite (SPD) matrices.
The distance is the length of the geodesic connecting M1 to M2.
Usage
1
dist_Riemann(M1, M2, eps = 1e-09)
Arguments
M1
a SPD Matrix
M2
a SPD matrix (same dims of M1).
eps
smallest eigenvalues. The count of eigenvalues smaller than eps is reported (just a quality control).
