Problem with Nested if statements

Hi everyone, I am using nested if statements to perform a subsection of my project but i don't like the way i have implemented it. I am sure that there will be some optimum way of doing the following task, so to avoid so many if statements. Thank you so much.

if any(idcabs==[1 2 3 4])
  if any(idabs==[1 2 5 6 9 10 13 14])
    idbeam1=1;
  else
    idbeam1=3;
  end
elseif any(idcabs==[5 6 7 8])
  if any(idabs==[1 2 5 6 9 10 13 14])
    idbeam1=3;
  else
    idbeam1=1;
  end
elseif any(idcabs==[9 10 11 12])
  if any(idabs==[1 2 3 4 5 6 7 8])
    idbeam1=2;
  else
    idbeam1=4;
  end
elseif any(idcabs==[13 14 15 16])
  if any(idabs==[1 2 3 4 5 6 7 8])
    idbeam1=4;
  else
    idbeam1=2;
  end
end

You should consider using ismember()

Hi Walter, even if a consider ismember(), i will still need those nested If statements. It will be just a change of functions from any() to ismemeber(). Do you mean something like this just for the first part.

[Aftab Ahmed Khan]

id1=ismember(idcabs,C1)
id2=ismember(idabs,S1)
if ~isempty(id1) && ~isempty(id2)
    idbeam1=1;
else
    idbeam1=3;
end
