Example (from Program LA_STEVR_EXAMPLE)

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

The call:
CALL LA_STEVR( D, E, W, Z, -5.0_wp, 5.0_wp, M=M )^7.5

W, Z and M on exit:

$$\hspace{-1.00 cm} \begin{array}{c} \\ \begin{array}{cc} {\b... ... \times 10^{-1} & 0 & 0 & 0 \\ \hline \end{array} \end{array}$$

The two eigenvalues of $A$ in the range $[-5, 5]$ and the corresponding eigenvectors are:

$$\begin{array}{c} \mbox{Eigenvalues} \\ \left( \begin{array... ...{-1} & 2.83907 \times 10^{-1} \end{array} \right). \end{array}$$
