Generate a list of arrows that follows one another

Ehud Behar

Posted 2 years ago

I have the following list of vectors: vecs = { {a1, a2}, {b1, b2}, {c1, c2}, {d1, d2}, {e1, e2}, {f1, f2} } and I want to generate the following list: { Arrow[{{0, 0}, {a1, a2}}], Arrow[{{a1, a2}, {b1, b2}}], Arrow[{{b1, b2}, {c1, c2}}], Arrow[{{c1, c2}, {d1, d2}}], Arrow[{{d1, d2}, {e1, e2}}], Arrow[{{e1, e2}, {f1, f2}}] } How can I do that?

I have the following list of vectors:

vecs = {
  {a1, a2},
  {b1, b2},
  {c1, c2},
  {d1, d2},
  {e1, e2},
  {f1, f2}
  }

and I want to generate the following list:

{
 Arrow[{{0, 0}, {a1, a2}}],
 Arrow[{{a1, a2}, {b1, b2}}],
 Arrow[{{b1, b2}, {c1, c2}}],
 Arrow[{{c1, c2}, {d1, d2}}],
 Arrow[{{d1, d2}, {e1, e2}}],
 Arrow[{{e1, e2}, {f1, f2}}]
 }

How can I do that?

Here is another way - a single line with several arrow heads: {Arrowheads[{0, 0.1, 0.1, 0.1, 0.1, 0.1}], Arrow[vecs]} EDIT: Works best if all vectors have the same lenght.
