multiIntersect

this function finds the common elements between all the vector arrays included in the input cell.

[commonElements, isCommon] = multiIntersect(x)

this function finds the common elements between all the vector arrays included in the input cell (x).

Each vector array in x has an optional length. The outputs:
1) commonElements includes the common elements between all the vector arrays.
2) isCommon is a cell with the same number of vector arrays as x, each of which has the same length as the corresponding vector array in x and indicates if the element is included in the commonElements or not.

Example)
x = { [11, 1, 19, 2, 11, 4, 6, 7, 9, 11] , [2, 1, 15, 5, 7, 11] , [1, 11, 7, 6, 9, 22] , [1, 7, 11] }
[commonElements, isCommon] = multiIntersect(x)

Answer)
commonElements = [1, 7, 11]
isCommon{1} = [1 1 0 0 1 0 0 1 0 1]
isCommon{2} = [0 1 0 0 1 1]
isCommon{3} = [1 1 1 0 0 0]
isCommon{4} = [1 1 1]
