Problem 67. Find common elements in matrix rows

Created by Cody Team in Community

Given a matrix, find all elements that exist in every row.

For example, given

 A =
     1 2 3 5
     9 2 5 9
     3 2 5 9
     1 2 1 5
     5 1 3 2

the answer would be the vector '2 5'. Elements should be returned sorted ascending.

Note there is no guarantee that there are any such elements; if there are none, the routine should return the empty set. Also, the matrix might contain NaNs, repeats, or very large or very small elements.
