if statement with changing values

I have a for loop that loops over vehicles. I have 2 houses. Each can have one or two cars:

ID1=178 or ID1=[178 180]

ID2=182 or ID2=[178 184}

I want to houses to never have the same vehicle.

I have tried this, but since ID1 and ID2 change size between 1 and 2 for each iteration it won't work. Can I overcome this somehow?

if ID1(1)==ID2(1)

continue

end

if ID1(2)==ID2(1)

continue

end

if ID1(2)==ID2(2)

continue

end

if numel(intersect(ID1,ID2))

Thanks, I will consider more houses later, does the same apply for:

%Removes all doubles

if numel(intersect(ID1,ID2,ID3))

continue

end

Intersect is only defined for two input arrays.
