Could some one please explain the logic behind the subroutine tqli(d,e,z) found on pg.1228 of numerical recipes in fortran. For this subroutine, d and e are one dimensional arrays and z is an optional multi-dimensional array(only used if also seeking for eigenvectors of matrix). The 3 modules, and the whole jacobi rotation technique has me confused. Thank you very much.
