Well, you got a point 
What confuses me still is this.
I think of the 1D tensor as a vector (is that right or this is some other kind of animal?)
A 2D tensor (1xN) could be transposed for example. but a 1D couldn’t.
So it’s not a vector in that sense.
You right about MATLAB, didn’t thought of it that  way but it only allows 2D,...,nD.
So now my question is why won’t a 1D tensor behave like a vector?
