public class Ssterf
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.

 *     ..
 *
 *  Purpose
 *  =======
 *
 *  SSTERF 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) REAL 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) REAL 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.
