How to compare between two cell array?

>> W={ [1 2] , [1 3] , [1 4] , [2 3] , [2 4] }

W =

1×5 cell array

[1×2 double] [1×2 double] [1×2 double] [1×2 double] [1×2 double]

>> F={ [1 2] , [1 3] , [1 4] }

F =

1×3 cell array

[1×2 double] [1×2 double] [1×2 double]

I want to compare each value in F if it is exist in W?

answer=cell2mat(cellfun(@(x) any(cellfun(@(y) isequal(x,y),W)),F,'uni',false))

Can I use loop for here to determine values that are in W, the result is not logical ,but the values are equal in W and F

[JESUS DAVID ARIZA ROYETH]

with :

W={ [1 2] , [1 3] , [1 4] , [2 3] , [2 4] }

F={ [1 2] , [1 8] , [1 4] }

this will show [1 0 1] logical, because [1 8] not is member of W

[Mira le]

C=[ ];

for i=1:length(W)

for j=1:length(F)

if F{j}==W{i}

C = [ C F{j} ];

end

end

end

it doesn't work

[JESUS DAVID ARIZA ROYETH]

C=[ ];
for i=1:length(W)
  for j=1:length(F)
      if isequal(F{j},W{i})
        C = [ C F{j} ];
   end
end
end

Thank you

Simpler using indexing:

>> X = ismember(cat(1,F{:}),cat(1,W{:}),'rows');
>> cat(1,F{X})
ans =
   1   2
   1   4
>> cat(2,F{X})
ans =
   1   2   1   4
