E.g.,

>> Per
Per =
     0     1     2     3
     0     2     3     1
     0     3     1     2
     3     2     0     1
     3     2     1     0
>> p
p =
     0     3     1     2
>> x = find(ismember(Per,p,'rows'))
x =
     3
>> Per(x,:)
ans =
     0     3     1     2
>> q = [3 2 0 1]
q =
     3     2     0     1
>> x = find(ismember(Per,q,'rows'))
x =
     4
>> Per(x,:)
ans =
     3     2     0     1
