WebBest. jack_but_with_reddit • 5 yr. ago. Yes, the eigenvalue of a 1x1 matrix is its only element. A 1x1 matrix is automatically diagonalized because the element a11 (the only element of a 1x1 matrix) is on the diagonal. Since a matrix in diagonal form has all of its eigenvalues on the diagonal, this means that the eigenvalue is the element.
