dgbequ example program

This example equilibrates the band matrix

A

given by

A = (\begin{array}{l} - 0.23 & 2.54 & - 3.66 \times 10^{- 10} & 0 \\ - 6.98 \times 10^{10} & 2.46 \times 10^{10} & - 2.73 & - 2.13 \times 10^{10} \\ 0 & 2.56 & 2.46 \times 10^{- 10} & 4.07 \\ 0 & 0 & - 4.78 \times 10^{- 10} & - 3.82 \end{array}) .

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