dpbequ example program

This example equilibrates the symmetric positive definite matrix

A

given by

A = (\begin{array}{l} 5.49 & 2.68 \times 10^{10} & 0 & 0 \\ 2.68 \times 10^{10} & 5.63 \times 10^{20} & - 2.39 \times 10^{10} & 0 \\ 0 & - 2.39 \times 10^{10} & 2.60 & - 2.22 \\ 0 & 0 & - 2.22 & 5.17 \end{array}) .

Details of the scaling factors and the scaled matrix are output.
