MATLAB: Extract cell depend on vector

Question

Dear all, I have vector a (1×7) and cell b (1×7), how can I extract each cell depend on elements equal in a?

 a= [ 1 2 3 3 4 5 6 6];
 b= { [1 2 3] [ 3 6] [ 5 6 7] [ 5 60] [ 5 6 5] [ 6 7 1 0] [ 88 99] [ 7 8 99] }

result should be:

 res= {[ 5 6 7] [ 5 60] [ 6 7 1 0] [ 88 99]}

Thanks…

Answer 1

The latest explanation is much clearer:

a = [ 3 2 1 3 6 5 4 6];
b = { [1 2 3] [ 3 6] [ 5 6 7] [ 5 60] [ 5 6 5] [ 6 7 1 0] [ 88 99] [ 7 8 99] };
result =  b(arrayfun(@(v) sum(a == v)>1, a))
