log_cholesky_log {riemtan} | R Documentation |
Compute the Log-Cholesky Logarithm
Description
This function computes the Riemannian logarithmic map using the Log-Cholesky metric for symmetric positive-definite matrices. The Log-Cholesky metric operates by transforming matrices via their Cholesky decomposition.
Usage
log_cholesky_log(sigma, lambda)
Arguments
sigma |
A symmetric positive-definite matrix of class |
lambda |
A symmetric positive-definite matrix of class |
Value
A symmetric matrix of class dspMatrix
, representing the tangent space image of lambda
at sigma
