NAME
       lis_array_cgs - calculate the QR	factorization with the classical Gram-
       Schmidt process

SYNOPSIS
       #include	"lis.h"

       LIS_INT	 lis_array_cgs(LIS_INT	n,  LIS_SCALAR	a[],  LIS_SCALAR  q[],
       LIS_SCALAR r[]);

DESCRIPTION

       r      The array	that stores upper-triangular matrix R of size n	* n

EXIT STATUS
       The following exit values are returned:

       0      The process is normally terminated
