double precision function dnrm2 (N, X, INCX)
double precision function dnrm2 (integer N, double precision, dimension(*) X, integer INCX)
DNRM2 returns the euclidean norm of a vector via the function name, so that DNRM2 := sqrt( x'*x )
N is INTEGER number of elements in input vector(s)
X is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
INCX is INTEGER storage spacing between elements of DX
