bures_wasserstein_exp {riemtan} | R Documentation |
Compute the Bures-Wasserstein Exponential
Description
This function computes the Riemannian exponential map using the Bures-Wasserstein metric for symmetric positive-definite matrices. The map operates by solving a Lyapunov equation and then constructing the exponential.
