Sorry I am a very beginner in Matlab but I hope someone could explain me where I made a mistake and how I could get the output requested. Thank you Matrix A 363×1226 Matrix B 363x1226 Qq=1:363 For C(qq,:) =intersect(A(qq,:), B(qq, :) ; End

It's not entirely clear to me how you want C to look. The number of rows should of course be the same, but what about the length of the rows? I assume the number of common elements will vary between rows. Depending on what you want, cells could be te solution:
A = [1 2 3; 4 5 6; 7 8 9; 10 11 12];
B = [3 2 4; 4 4 6; 6 7 8; 13 14 15];
C = cell(3,1);
for i = 1:size(A,1)
C{i} = intersect(A(i,:),B(i,:));
end
If this is not what you're looking for, please try to be more specific.

Thank you very much for helping me. Yes the length of each row can vary depending on the number of the elements in common.

Yes, the above provided example should give some insight in to getting your output
