DSYSV Example

To solve the equations

Ax = b,

where A is the symmetric matrix

A = $$\left(\vphantom{ \begin{array}{rrrr} -1.81 & 2.06 & 0.63 & -1.1... ...63 & 1.87 & -0.21 & 3.87 \\ -1.15 & 4.20 & 3.87 & 2.07 \end{array} }\right.$$$$\begin{array}{rrrr} -1.81 & 2.06 & 0.63 & -1.15 \\ 2.06 & 1.1... ... \\ 0.63 & 1.87 & -0.21 & 3.87 \\ -1.15 & 4.20 & 3.87 & 2.07 \end{array}$$$$\left.\vphantom{ \begin{array}{rrrr} -1.81 & 2.06 & 0.63 & -1.1... ...63 & 1.87 & -0.21 & 3.87 \\ -1.15 & 4.20 & 3.87 & 2.07 \end{array} }\right)$$  and  b = $$\left(\vphantom{ \begin{array}{r} 0.96 \\ 6.07 \\ 8.38 \\ 9.50 \end{array} }\right.$$$$\begin{array}{r} 0.96 \\ 6.07 \\ 8.38 \\ 9.50 \end{array}$$$$\left.\vphantom{ \begin{array}{r} 0.96 \\ 6.07 \\ 8.38 \\ 9.50 \end{array} }\right)$$.

Details of the factorization of A are also output.
