Example program for dorglq

This example forms the leading 4 rows of the orthogonal matrix Q from the LQ factorization of the matrix A, where
A = -5.42 3.28 -3.68 0.27 2.06 0.46 -1.65 -3.40 -3.20 -1.03 -4.06 -0.01 -0.37 2.35 1.90 4.31 -1.76 1.13 -3.15 -0.11 1.99 -2.70 0.26 4.50 .  
The rows of Q form an orthonormal basis for the space spanned by the rows of A.
