To solve the equations

AX = B,

where A is the symmetric positive definite matrix

A = $$\left(\vphantom{ \begin{array}{rrrr} 4.16 & -3.12 & 0.56 & -0.1... ...56 & -0.83 & 0.76 & 0.34 \\ -0.10 & 1.18 & 0.34 & 1.18 \end{array} }\right.$$$$\begin{array}{rrrr} 4.16 & -3.12 & 0.56 & -0.10 \\ -3.12 & 5.... ... \\ 0.56 & -0.83 & 0.76 & 0.34 \\ -0.10 & 1.18 & 0.34 & 1.18 \end{array}$$$$\left.\vphantom{ \begin{array}{rrrr} 4.16 & -3.12 & 0.56 & -0.1... ...56 & -0.83 & 0.76 & 0.34 \\ -0.10 & 1.18 & 0.34 & 1.18 \end{array} }\right)$$  and  B = $$\left(\vphantom{ \begin{array}{rr} 8.70 & 8.30 \\ -13.35 & 2.13 \\ 1.89 & 1.61 \\ -4.14 & 5.00 \end{array} }\right.$$$$\begin{array}{rr} 8.70 & 8.30 \\ -13.35 & 2.13 \\ 1.89 & 1.61 \\ -4.14 & 5.00 \end{array}$$$$\left.\vphantom{ \begin{array}{rr} 8.70 & 8.30 \\ -13.35 & 2.13 \\ 1.89 & 1.61 \\ -4.14 & 5.00 \end{array} }\right)$$.

Error estimates for the solutions, information on equilibration and an estimate of the reciprocal of the condition number of the scaled matrix A are also output.
