Example program for dgbsvx

This example solves the equations
AX=B ,  
where A  is the band matrix
A = -0.23 2.54 -3.66 0.00 -6.98 2.46 -2.73 -2.13 0.00 2.56 2.46 4.07 0.00 0.00 -4.78 -3.82   and   B = 4.42 -36.01 27.13 -31.67 -6.14 -1.16 10.50 -25.82 .  
Estimates for the backward errors, forward errors, condition number and pivot growth are also output, together with information on the equilibration of A .
