SLA_DVN - Normalize Vector +   +

+
+
ACTION: +
Normalize a 3-vector, also giving the modulus (double precision). +
CALL: +
CALL sla_DVN (V, UV, VM) +

+

+
GIVEN: +
+
+ + + + + +
VD(3)vector
+

+
RETURNED: +
+
+ + + + + + + + + +
UVD(3)unit vector in direction of V
VMDmodulus of V
+

+
NOTE: +
If the modulus of V is zero, UV is set to zero as well. +
