This invariant direction does not necessarily give the transformation’s direction of greatest effect, however. The singular values σ 1 ,…, σ n of a are the nonnegative square roots of the eigenvalues of the symmetric positive semidefinite matrix ata. By multiplying a by its transpose, you get a matrix that has the same number of rows as.
