Example (from Program LA_SPSVX_EXAMPLE)

The results below are computed with $\epsilon = 1.19209 \times 10^{-7}$.
Matrices $A$ and $B$ are the same as in Example 2 for LA_SPSV.

The call:
CALL LA_SPSVX( AP, B, X, 'L', AFP, IPIV)

${\bf AFP}$ and ${\bf IPIV}$ on exit:

$$\hspace{-1.00 cm} \begin{array}{c} {\bf AFP} \\ \begin{arr... ... -4 \\ -4 \\ 3 \\ 4 \\ 5 \\ \hline \end{array} \end{array}$$

The solution vector $x$ is identical to that in Example 2 for LA_SPSV.
