MATLAB: How to do intersection between 3 vectors

matrix manipulation

hello, I want to obtain the intersection between 3 vector as fellow :
 A = [1,3,8,5];
 B = [4,1,6,8];
 C=  [5,8,7,1];
 ABC_inter=intersect(A,B,C,'stable')
the result should be :
   ABC_inter=[1,8]
But I obtain this error, please help me to solve this problem and thanks in advance.
   Error using intersect (line 101)
Invalid input. Valid flags are 'rows', 'stable', 'sorted', 'legacy', 'R2012a'.
