Example 3 (from Program LA_SBEVD_EXAMPLE)

Matrix $A$ as in Example 2.

Array ${\bf AB}$ on entry:

$$\begin{array}{cc} {\bf AB} \\ \begin{array}{\vert rrrrr\v... ...& 0 \\ -5 & 4 & -1 & 0 & 0 \\ \hline \end{array} \end{array}$$

The call:
CALL LA_SBEVD( AB, W, 'L', Z, INFO )
Z and INFO on exit:

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

The eigenvectors of $A$ are:

$$\left( \begin{array}{l@{\hspace{1mm}}l@{\hspace{1mm}}l@{\hsp... ... 10^{-1} & \;\;\; 1.55729 \times 10^{-1} \end{array} \right)$$
