Example 2 (from Program LA_STEVD_EXAMPLE)

Matrix $A$ as in Example 1.

The call:
CALL LA_STEVD( D, E, Z, INFO )

${\bf Z}$, and ${\bf INFO}$ on exit (D as in Example 1):

$$\begin{array}{c} \\ \begin{array}{c} {\bf Z} \\ \begin{arra... ...\ \\ \begin{array}{c} {\bf INFO} = 0 \end{array} \end{array}$$

The eigenvectors of $A$ are:

$$\left( \begin{array}{r@{\hspace{2mm}}r@{\hspace{2mm}}r@{\hsp... ...^{-2} & \;\;\; 7.22054 \times 10^{-1} \\ \end{array} \right)$$
