If I have N vectors of different length how would i isolate and return the vector of the smallest length? I dont care what the length is i just need which is the smallest one.

If you "have them" in cell array form, then you could do something like this:
>> vectors={[3 4 5],[1,2],[5 6 7 8]}
vectors =
1×3 cell array
{1×3 double} {1×2 double} {1×4 double}
>> [~,imin]=min(cellfun('length',vectors));
>> smallest=vectors{imin}
smallest =
1 2

Well, what form were they in? Just separate variables? If so, you need to check their lengths one at a time.

Or, you will have to load them into a cell array manually,
vectors={v1,v2,v3,...}
