Example (from Program LA_STEVX_EXAMPLE)

The results below are computed with $\epsilon = 1.19209 \times 10^{-7}$.
The matrix $A$ is the same as Example 1 for LA_STEV.

The call:
CALL LA_STEVX( D, E, W, IL
=1, IU=3, ABSTOL=1.0E-2_wp ) 7.4

Array W on exit and the first three eigenvalues of matrix $A$:

\begin{displaymath}
\begin{array}{cc} {\bf W} \\
\begin{array}{\vert r\vert} ...
...ay}{r}
-6.99685 \\ -3.67165 \\ 4.20190
\end{array} \right).
\end{displaymath}
