Functions
void	svd (RealMatrix &matrix, RealVector &singular_vals, RealMatrix &v_trans, bool compute_vectors=true)
	Compute the SVD of an arbitrary matrix A = USV^T. More...
void	singular_values (RealMatrix &matrix, RealVector &singular_values)
	compute the singular values without storing any singular vectors (A will be destroyed)
int	qr (RealMatrix &A)
	Compute an in-place QR factorization A = QR. More...
int	qr_rsolve (const RealMatrix &q_r, bool transpose, RealMatrix &rhs)
	Perform a multiple right-hand sides Rinv * rhs solve using the R from a qr factorization. More...
double	det_AtransA (RealMatrix &A)
	Use SVD to compute det(A'*A), destroying A with the SVD.
void	symmetric_eigenvalue_decomposition (const RealSymMatrix &matrix, RealVector &eigenvalues, RealMatrix &eigenvectors)
	Computes the eigenvalues and, optionally, eigenvectors of a real symmetric matrix A. More...
