WebJun 23, 2024 · 2 Answers Sorted by: 2 When you multiply a 3 × 1 vector by a 1 × 3 vector the result is ( 3 × 1) ⋅ ( 1 × 3) = 3 × 3. On the other hand, when you multiply a 1 × 3 vector by a 3 × 1 vector, you get ( 1 × 3) ⋅ ( 3 × 1) = 1 × 1 (this is the inner product, aka the dot product) The image in this answer is the easiest way to visualize this, imo. Share WebWhether you represent the gradient as a 2x1 or as a 1x2 matrix (column vector vs. row vector) does not really matter, as they can be transformed to each other by matrix transposition. If a is a point in R², we have, by definition, that the gradient of ƒ at a is given by the vector ∇ƒ(a) = (∂ƒ/∂x(a), ∂ƒ/∂y(a)),provided the partial derivatives ∂ƒ/∂x and ∂ƒ/∂y …
