How to make statements intersect

How can I make if command's statements intersect and after that receive the result. For example the answer for this code is 'noyesno' ....but I want it to be no, cause not all the elements of a and b are equal.

n=3
a=[0 1 2]
b=[1 1 3]
i=1
for i=1:n
  if a(i)==b(i)
      fprintf ('yes')
  else 
        fprintf ('no')
end
end
   

Answer 1

a=[0 1 2];
b=[1 1 3];

if all(a==b)
    fprintf ('yes')
else
    fprintf ('no')
end

Thank you I this is all I wanted !!!

Answer 2

[Bhaskar R]

n=3;    % length of the your vector i guess  
a=[0 1 2];
b=[1 1 3];
% depends on n value
is_intersect = sum(a(1:n)==b(1:n))==n;
% if a and b vectors are same length
is_intersect = sum(a==b)==length(a);
if is_intersect
    fprintf ('yes');
else
    fprintf ('no');
end

Hope i got you !!

It's more complicated than the answer above but also very useful, thank you !
