Difference between tensor and vector?

Vitani11 · Feb 27, 2017

δ_ij is the Kronecker delta - is this considered a tensor or vector? I know it means the identity when i=j so I'm going to guess tensor because it's a matrix rather than just a vector but I want to make sure. A matrix is a rank 2 tensor and a vector is a rank 1 and a scalar is a rank 0? How does that work?

Not sure what you mean by "how does it work" because you're right with what you've said.
