Obtain elements that are common to two vectors

Given vector or list \(d=[-9,1,3,-3,50,7,19],\) \(t=[0,7,2,50]\), ﬁnd the common elements.

Mathematica

d = {-9,1,3,-3,50,7,19}; 
t = {0,7,2,50}; 
Intersection[d,t]

Out[412]= {7,50}

Matlab

d=[-9 1 3 -3 50 7 19]; 
t =[0 7 2 50]; 
intersect(t,d)

ans = 
     7    50

Maple

d := {-9,1,3,-3,50,7,19}; 
t := {0,7,2,50}; 
d intersect t;

{7, 50}
