To solve the equations

AX = B,

where A is the general matrix

A = $$\left(\vphantom{ \begin{array}{rrrr} 1.80 & 2.88 & 2.05 & -0.89... ...-2.69 & -2.90 & -1.04 \\ -1.11 & -0.66 & -0.59 & -0.80 \end{array} }\right.$$$$\begin{array}{rrrr} 1.80 & 2.88 & 2.05 & -0.89 \\ 525.00 & -2... ... 1.58 & -2.69 & -2.90 & -1.04 \\ -1.11 & -0.66 & -0.59 & -0.80 \end{array}$$$$\left.\vphantom{ \begin{array}{rrrr} 1.80 & 2.88 & 2.05 & -0.89... ...-2.69 & -2.90 & -1.04 \\ -1.11 & -0.66 & -0.59 & -0.80 \end{array} }\right)$$  and  B = $$\left(\vphantom{ \begin{array}{rr} 9.52 & 18.47 \\ 2435.00 & 225.00 \\ 0.77 & -13.28 \\ -6.22 & -6.21 \end{array} }\right.$$$$\begin{array}{rr} 9.52 & 18.47 \\ 2435.00 & 225.00 \\ 0.77 & -13.28 \\ -6.22 & -6.21 \end{array}$$$$\left.\vphantom{ \begin{array}{rr} 9.52 & 18.47 \\ 2435.00 & 225.00 \\ 0.77 & -13.28 \\ -6.22 & -6.21 \end{array} }\right)$$.

Error estimates for the solutions, information on scaling, an estimate of the reciprocal of the condition number of the scaled matrix A and an estimate of the reciprocal of the pivot growth factor for the factorization of A are also output.
