```DSTERF(1)		 LAPACK routine (version 3.2)		     DSTERF(1)

NAME
DSTERF  -  computes  all	 eigenvalues of a symmetric tridiagonal matrix
using the Pal-Walker-Kahan variant of the QL or QR algorithm

SYNOPSIS
SUBROUTINE DSTERF( N, D, E, INFO )

INTEGER	  INFO, N

DOUBLE	  PRECISION D( * ), E( * )

PURPOSE
DSTERF computes all eigenvalues of a symmetric tridiagonal matrix using
the Pal-Walker-Kahan variant of the QL or QR algorithm.

ARGUMENTS
N       (input) INTEGER
The order of the matrix.	 N >= 0.

D       (input/output) DOUBLE PRECISION array, dimension (N)
On  entry,  the	n diagonal elements of the tridiagonal matrix.
On exit, if INFO = 0, the eigenvalues in ascending order.

E       (input/output) DOUBLE PRECISION array, dimension (N-1)
On entry, the (n-1) subdiagonal	elements  of  the  tridiagonal
matrix.	On exit, E has been destroyed.

INFO    (output) INTEGER
= 0:  successful exit
< 0:  if INFO = -i, the i-th argument had an illegal value
>  0:  the algorithm failed to find all of the eigenvalues in a
total of 30*N iterations; if INFO = i, then  i  elements	 of  E
have not converged to zero.
