Required methods

fn detc(&self) -> Self::Output

Computes the determinant of the Hermitian (or real symmetric) positive definite matrix.

fn ln_detc(&self) -> Self::Output

Computes the natural log of the determinant of the Hermitian (or real symmetric) positive definite matrix.

This method is more robust than .detc() to very small or very large determinants since it returns the natural logarithm of the determinant rather than the determinant itself.
