MATLAB: How to check whether a vector belongs to a matrix

construct new matrixvector in matrix

I have a vector of 
P_1=  [1	3	4	11	10	15	19	0	0	0	0	0	0	0	0	0	0	0	0	0]
and I want to see if each sequence of steps can be found in a larger matrix 
N= [1	2
1	3
2	1
2	6
3	1
3	4
3	12
4	3
4	5
4	11]
.
I want to construct a new matrix Q that states if P_1(1:2) belongs to a row in N, then it should give a 1, otherwise 0. Therefore, I should get a Q matrix of [0 1 0 0 0 1 0 0 0 1]. I already have the following:
for z=1:19
        for x= 1:10
            if P_1(z:z+1)==N(x,1:2) 
                Q(x,1)=1
            else Q(x,1)=0
            end
        end
    
end

Best Answer

Psteps=[P_1(1:end-1);P_1(2:end)].';
Q=ismember(N,Psteps,'rows').'
