Functions
real	num::kernel::subspace::mgs_orthogonalize (const std::vector< Vector > &basis, Vector &v, std::vector< real > &h, idx k)
	Modified Gram-Schmidt: orthogonalize v against basis[0..k-1].
real	num::kernel::subspace::mgs_orthogonalize (const Matrix &basis, idx k, Vector &v)
	Modified Gram-Schmidt: orthogonalize v against columns 0..k-1 of a column-stored basis matrix.
real	num::kernel::subspace::arnoldi_step (const LinearOp &A, std::vector< Vector > &basis, std::vector< real > &h, idx k, Vector &scratch, real breakdown_tol=real(1e-14))
	One Arnoldi step: expand the orthonormal basis by one vector.
