Vectors vs Tensors
Vectors vs Tensors — Are They the Same? Short answer: related but not identical. A vector is a special case of a tensor. The math hierarchy Term Rank Shape example Scalar 0 a single number Vector 1 [d] — a 1D array Matrix 2 [m, n] — a 2D array Tensor N [d1, d2, ..., dN] — generic N-dimensional array Every vector is a tensor (specifically, a rank-1 tensor). Not every tensor is a vector. ...
