Example 2 (from Program LA_HPEV_EXAMPLE)

The results below are computed with $\epsilon = 1.19209 \times 10^{-7}$.


\begin{displaymath}
A = \left( \begin{array}{ccccc}
-1 & 4+i & 2-2i & 2 & -4+i...
...2 & -4 \\
-4-i & 4-2i & 3+2i & -4 & -1
\end{array} \right),
\end{displaymath}

Array ${\bf AP}$ on entry (${\bf UPLO} =$ 'U' by default):

\begin{displaymath}
\begin{array}{cc} {\bf AP} \\
\begin{array}{\vert ccccccc...
..., 3) &
(2 , 0) &
(1, -2) \\
\hline \end{array} \end{array}\end{displaymath}


\begin{displaymath}
\begin{array}{cc} { \bf AP} \ (continued) \\
\begin{array}{...
... -2) &
(-4 , 0) &
(-1 , 0) \\
\hline \end{array} \end{array}\end{displaymath}

The call:
CALL LA_HPEV( AP, W )


\begin{displaymath}
\begin{array}{c} \mbox{Array {\bf W} on exit:} \\
\begin{...
...4.40089 \\ \;\;\; 10.3534 \\
\end{array} \right). \end{array}\end{displaymath}
