WebIt can be used as a replacement for longhand writing of equations or matrix representation. A matrix is more valuable for representing the storage of values in the system, but for writing equations in a compact form, and especially for higher order tensors, indicial notation is superior. Unless otherwise stated, all indices go between 1 and 3. Web4. Using positional index notation with tensors is common. For example, the following simple equation from Carroll's Spacetime and Geometry text (eq. 3.146): R = R μ μ = g μ ν R μ ν. Where the Ricci scalar summation, R μ μ uses positional offsets on the upper and lower indices. So, I think I understand the usage and motivation for this ...

But as we have a differential operator, we don't need to use the product rule. We get: ∇ ⋅ (∇ × →F) = ϵijk∂i∂jFk. " - Tensors used as indices

Web4 Jan 2024 · As for size, this can imply a particular axis or the entire size of the tensor. The three_dimensional_tensor has a total size of 2 * 2 * 3 = 12. However, the size of axis 0 is 2 (the first 2 in the shape). The size of axis 1 is 2, and the size of axis 2 is 3. The total size is simply the number of elements in the tensor.
