compute_log_determinant()

double stan::math::internal::LUSolver::compute_log_determinant ( ) const

inline

Compute log determinant from LU factorization.

Note

This uses the diagonal of the combined LU matrix produced by Eigen (equivalently the diagonal of U). It does not account for the sign of the permutation; callers assume det(B) > 0 in the Laplace correction.

Returns

Sum of log of the LU diagonal entries.
