19// Class Ali3VectorObj
20// Handling of 3-vectors in various reference frames.
21//
22// This class is meant to provide an Ali3Vector object which is derived
23// from TObject such that it can be stored in e.g. TObjArray etc...
24// and that it can be written out using the ROOT I/O machinery.
25//
26// Example :
27// =========
28//
29// Float_t a[3]={1,2,3};
30// Float_t ea[3]={0.01,0.02,0.03};
31// Float_t b[3]={4,5,6};
32// Float_t eb[3]={0.04,0.05,0.06};
33//
34// Ali3Vector v,w;
35//
36// v.SetVector(a,"car");
37// v.SetErrors(ea,"car");
38// w.SetVector(b,"car");
39// w.SetErrors(eb,"car");
40//
41// Ali3Vector cross=v.Cross(w);
42//
43// Ali3Vector add=v+w;
44//
45// Ali3VectorObj vec1(cross);
46//
47// Ali3VectorObj vec2;
48// vec2.Load(add);
49//
84bb7c66 50// vec1.Data();
51// vec2.Data();
