NOTE ON THE IMPROVEMENT OF APPROXIMATE LATENT ROOTS AND MODAL COLUMNS OF A SYMMETRICAL MATRIX
W.J. Goodey · The Quarterly Journal of Mechanics and Applied Mathematics · 1955
The method given below for the improvement of an approximate set of latent roots and modal columns of a symmetrical matrix is essentially the same as Jahn's second method described in (1), but the proof is here set out entirely in matrix notation. The present paper is, in fact, the counterpart of the notes by Collar (2) relating to Jahn's first method.
