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
     Calculate	the  QR  factorization	QR=A  with  the  classical  Gram-Schmidt
     process.

INPUT
     n	    The size of the matrices

     a	    The array that stores matrix A of size n * n

OUTPUT
     q	    The array that stores orthogonal matrix Q of size n * n

     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

     unspecified
	    An error occurred
