NAME
       TESTING/EIG/ssxt1.f

SYNOPSIS
   Functions/Subroutines
       real function ssxt1 (ijob, d1, n1, d2, n2, abstol, ulp, unfl)
           SSXT1

Function/Subroutine Documentation
   real function ssxt1 (integer ijob, real, dimension( * ) d1, integer n1,
       real, dimension( * ) d2, integer n2, real abstol, real ulp, real unfl)
       SSXT1

       Purpose:


            SSXT1  computes the difference between a set of eigenvalues.
            The result is returned as the function value.

            IJOB = 1:   Computes   max { min | D1(i)-D2(j) | }
                                    i     j

            IJOB = 2:   Computes   max { min | D1(i)-D2(j) | /
                                    i     j
                                         ( ABSTOL + |D1(i)|*ULP ) }

       Parameters
           IJOB

                     IJOB is INTEGER
                     Specifies the type of tests to be performed.  (See above.)

           D1

                     D1 is REAL array, dimension (N1)
                     The first array.  D1 should be in increasing order, i.e.,
                     D1(j) <= D1(j+1).

           N1

                     N1 is INTEGER
                     The length of D1.

           D2

                     D2 is REAL array, dimension (N2)
                     The second array.  D2 should be in increasing order, i.e.,
                     D2(j) <= D2(j+1).

           N2

                     N2 is INTEGER
                     The length of D2.

           ABSTOL

                     ABSTOL is REAL
                     The absolute tolerance, used as a measure of the error.

           ULP

                     ULP is REAL
                     Machine precision.

           UNFL

                     UNFL is REAL
                     The smallest positive number whose reciprocal does not
                     overflow.
