What is the rank of a vector? - Mathematics Stack Exchange

Web22 apr. 2024 · Briefly, any matrix is a tensor of rank 2. In general, a tensor is going to "eat" a certain number of vectors and output a real number; the number of vectors it eats is the rank of the tensor. (More generally, it can eat a certain number of vectors and spit out another number of vectors. The rank will be the sum of those numbers.) – Ted Shifrin.
