MATLAB: Does something similar to ‘intersect’ command exists for more than 2 vectors

intersect

Hi,

There are 5 row vectors with different(or same) number of elements. The problem is to pick out the 'intersecting' elements from these 5 vectors.

'intersect(A,B)' works with only 2 vectors. Is there a command/procedure for more than 2 vectors?

Thanks.

You could call INTERSECT multiple times:

A = [1 2 3 4 5];B = [3 7 8 9 5];C = [5 0 22 3 77];
F = intersect(intersect(A,B),C)

n = cellfun(@numel,A);
ii = cumsum(n);
x = [A{:}];
out = x(B+[0;ii(1:end-1)]);

Use the "intersect" function as follows:

>> [C,ia,ib] = intersect(A,B, 'stable');
