Example (from Program LA_SYEVR_EXAMPLE)

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

The call:
CALL LA_SYEVR( A, W, IL
=1, IU=2, M=M )

W and M on exit:

\begin{displaymath}\hspace{-1.00 cm}
\begin{array}{c} \\ \begin{array}{c} {\bf...
...y} \\ \\
\begin{array}{c} {\bf M} = 2 \end{array} \end{array} \end{displaymath}

The first two eigenvalues of matrix $A$ are: $\left( \begin{array}{ll} -1.124612 \times 10^{1} & -6.24975 \end{array} \right)$.
