log_cholesky_exp {riemtan} | R Documentation |
Compute the Log-Cholesky Exponential
Description
This function computes the Riemannian exponential map using the Log-Cholesky metric for symmetric positive-definite matrices. The map operates by transforming the tangent vector via Cholesky decomposition of the reference point.
