Parallelogram rule for vectors

Is there some methods to calculate the summation of these four red vectors showed below?

For example,

V1 = [4,3];
V2 = [-3,4];
V3 = [-2,-1];
V4 = [1,-5];

Any helps would be appreciated.

Vtot = V1+V2+V3+V4

I guess no.

If we name V1=V2=V3=V4=[1,1], the result is [4,4] based on your approach.

But if we draw the vectors on the map I showed in the original question, the answer should not be [4,4].

I suppose the most important thing is how can MATLAB run it based on the parallelogram rule.

Thanks for your help.

V1+V2+V3+V4 (Sun of vectors) IS [4,4] What do you want to have?

I am sorry that I haven't explained it clearly. Maybe the link below can help me explain what I want.

Now, I have a thought to programming in MATLAB, and I suppose I can get the wanted result. But I still need to try it later. For the path, I attached here as a picture. But I am still wondering whether there is some functions or package from MATLAB to solve my problems directly.
