How do I compare the elements of two vectors 1 by 1?

I am trying to manually write a set intersection function in matlab. I need to compare all of the elements of each vector. Right now for the comparison I have an for loop with an if statement inside:

for i = 1:length(uset1)
  if uset1(i) == uset2(i)   
     result = i;

uset1 and uset2 are single row vectors where no elements are duplicated. Whenever I try to run I get an error saying that '==' is an undefined operator for input arguments of type 'cell'. Is there another way to compare individual elements of two vectors?

Use curly brackets

uset1{i} == uset2{i}

You can avoid for loop

out=find(cellfun(@(x,y) x==y,uset1,uset2))

Another approach:

uset1 = {randi(9, 1, 20)};                                  % Create Data
uset2 = {randi(9, 1, 20)};                                  % Create Data

LV = cellfun(@ne, uset1, uset2, 'Uni',0);                   % Logical Vector
out = find(~LV{:});                                         % Indices Of Equal Elements
