Why do I get "Subscript indices must either be real positive integers or logicals."??

Hello,

So I have 3 arrays with double variables and I want to merge them into one array, each one of them into a collumn of Wine array. This is my code:

for i=0:178
  if i==49
      i=60;
  end
  if i==108
      i=131;
  end
  Wines=[TotalPhelons(i,:);Flavanoids(i,:);NonflavanoidPhenols(i,:)];
end

Why do I get this error? [I want specific variables from each array to import into Wines.]

Thanks in advance!

I would say that error message is pretty self-explanatory surely! It is always useful to actually interpret an error message and understand what it means rather than just look at it as "an error" that you don't know what to do with.

What you said is true and I agree with you. But I was in a situation everyone of us have been, "Why doesn't it work?". I've spent an hour and I completely ignored it, obviously a syntax error, believing it has something to do with array types. Nevertheless, thanks again everyone!

Because of this line:

 i=0:178

You start your indices from zero, but MATLAB indices start from one. Read the error message: it tells you what the problem is.
