How write a symbol of the circle in the Latex?

  • There was also a question about a matrix with diagonal lines like that (although in the opposite direction), but I can't find it. – Alenanno May 31 '15 at 1:01
  • Can you be more specific about what it is you want? Drawing a circle is easy, but it's not as complicated as putting text in that circle – and that's saying quite a thing, because the latter is easy, too. :-) – Sean Allred May 31 '15 at 2:08
  • @Alenanno It was about diagonal arrows (easy change) tex.stackexchange.com/questions/38169/… – R. Schumacher May 31 '15 at 2:27
  • @R.Schumacher Oh that's another one but the one I was referring to was with a Tikz Matrix (done with a foreach) and it had couples like (0,0), (1,1), and so on. :D – Alenanno May 31 '15 at 9:15
