Example 3 (from Program LA_HPEVD_EXAMPLE)

Matrix $A$ as in Example 2.

Array ${\bf AP}$ on entry:

$$\begin{array}{cc} {\bf AP} \\ \begin{array}{\vert ccccccc... ..., 0) & (-5 , 2) & (1 , 2) \\ \hline \end{array} \end{array}$$

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

The call:
CALL LA_HPEVD( A, W, 'L', Z, INFO )

Z and INFO on exit:

$$\begin{array}{c} {\bf Z} \\ \begin{array}{\vert ll} \hlin... ...-1},-4.23193 \times 10^{-1}) \\ \hline \end{array} \end{array}$$

$$\begin{array}{c} {\bf Z \ continued} \\ \begin{array}{ll}... ...-1},-4.67133 \times 10^{-1}) \\ \hline \end{array} \end{array}$$

$$\begin{array}{cc} {\bf Z \ continued} \\ \begin{array}{l\ve... ...y} \hspace{1.50 cm} \begin{array}{c} {\bf INFO} = 0 \end{array}$$

The eigenvectors of $A$ are:

$$\left( \begin{array}{ll} \;\;\; 3.98486 \times 10^{-1} & \;... ...\times 10^{-1} - 4.23193 \times 10^{-1}i \end{array} \right.$$

$$\left. \begin{array}{ll} \;\;\; 7.03213 \times 10^{-1} & \;... ... \times 10^{-1} - 4.67133 \times 10^{-1}i \end{array} \right.$$

$$\left. \begin{array}{ll} \;\;\; 3.90130 \times 10^{-1} \\ ... ... \times 10^{-1} - 2.80089 \times 10^{-1}i \end{array} \right)$$
