In riemtan: Riemannian Metrics for Symmetric Positive Definite Matrices

Compute the Bures-Wasserstein Logarithm

Description

This function computes the Riemannian logarithmic map using the Bures-Wasserstein metric for symmetric positive-definite matrices.

Usage

bures_wasserstein_log(sigma, lambda)

Arguments

sigma	A symmetric positive-definite matrix of class dppMatrix, representing the reference point.
lambda	A symmetric positive-definite matrix of class dppMatrix, representing the target point.

Value

A symmetric matrix of class dspMatrix, representing the tangent space image of lambda at sigma.
