NAME
     lis_array_matvect - calculate the matrix vector product

SYNOPSIS
     #include "lis.h"

     LIS_INT   lis_array_matvect(LIS_INT  n,  LIS_SCALAR  a[],	LIS_SCALAR  x[],
     LIS_SCALAR y[], LIS_INT op);

DESCRIPTION
     Calculate the matrix-vector product A^Tx.

INPUT
     n	    The size of the matrix and vectors

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

     x	    The array that stores vector x of size n

     y	    The array that stores vector y of size n

     op

	    LIS_INS_VALUE
		   y = A^Tx

	    LIS_SUB_VALUE
		   y = y - A^Tx

OUTPUT
     y	    y

EXIT STATUS
