Determinant of Hermitian (or real symmetric) positive definite matrix

Required Methods

fn detc_into(self) -> Self::Output

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

fn ln_detc_into(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_into() to very small or very large determinants since it returns the natural logarithm of the determinant rather than the determinant itself.
