Dear all How to find common or equal elements between every two successive vectors (not equal in length) in a cell array, e.g.

str =

Columns 1 through 5
    [1x5 double]    [1x37 double]    [1x63 double]    [1x39 double]    [1x75 double]
Column 6
    [1x75 double]

str={[1 2 3 4],[2 3 5 6],[5 10 20],[25 40]}
n=numel(str);
out=cell(n-1,1);
for k=1:n-1
 out{k}=intersect(str{k},str{k+1})
end

Sounds like you have a script named intersect.m

You should rename your script. It's not a good idea to name custom functions and scripts the same as MATLAB's builtin functions and scripts, because name conflict issue will arise.

Another (less desirable) workaround is to use the function "builtin".

str={[1 2 3 4],[2 3 5 6],[5 10 20],[25 40]}
n=numel(str);
out=cell(n-1,1);
for k=1:n-1
 out{k}=builtin('intersect',str{k},str{k+1})
end

Thanx, I used the builtin function but I got this results

The code

vectors = 
      {1x5 cell}    {1x37 cell}    {1x63 cell}    {1x39 cell}
q = length(vectors)
for qq= 1:q-1
      terminals{qq} = builtin('intersect',vectors{qq}, vectors{qq+1})
end

The results

Error using builtin
Cannot find builtin function 'intersect'
Error in Area6 (line 67)
      terminals{qq} = builtin('intersect',vectors{qq}, vectors{qq+1})
