When I am trying to use the "ismember" command in 2020a, I get werid stuffs. e.g.,

A = [1 2 3; 
    4 5 6; 
    7 8 9];
B = [4 5 6];
[Result,LocResult] = ismember(B,A,'rows')

is giving me

Result =
  logical
   0
LocResult =
     0

Am i doing something wrong here? I was expecting to get

Result =
       1
LocResult =
       2
