Example program for dgecon

This example estimates the condition number in the 1-norm of the matrix A, where
A= 1.80 2.88 2.05 -0.89 5.25 -2.95 -0.95 -3.80 1.58 -2.69 -2.90 -1.04 -1.11 -0.66 -0.59 0.80 .  
Here A is nonsymmetric and must first be factorized by dgetrf. The true condition number in the 1-norm is 152.16.
