Function rgsl::linear_algebra::complex_LU_lndet

pub fn complex_LU_lndet(lu: &MatrixComplexF64) -> f64

These functions compute the logarithm of the absolute value of the determinant of a matrix A, \ln|\det(A)|, from its LU decomposition, LU. This function may be useful if the direct computation of the determinant would overflow or underflow.
