Example 1 (from Program LA_GESV_EXAMPLE)

$$A = \left( \begin{array}{rrrrr} 0 & 2 & 3 & 5 & 4 \\ 1 &... ...2 & 78 \\ 22 & 44 & 66 \\ 22 & 44 & 66 \end{array} \right)$$

Arrays ${\bf A}$ and ${\bf B}$ on entry:

$$\begin{array}{cc} {\bf A} \\ \begin{array}{\vert rrrrr\ve... ...2 & 44 & 66 \\ 22 & 44 & 66 \\ \hline \end{array} \end{array}$$

The call:
CALL LA_GESV( A, B )

${\bf B}$ on exit:

$$\begin{array}{cc} {\bf B} \\ \begin{array}{\vert rrr\vert... ...1.00000 & 2.00000 & 3.00000 \\ \hline \end{array} \end{array}$$

The solution of the system $A\,X = B$ is:

$$X = \left( \begin{array}{rrr} 1.00000 & 2.00000 & 3.00000 ... ...3.00000 \\ 1.00000 & 2.00000 & 3.00000 \end{array} \right).$$
