It should be noted here that torch.multiply() is just an alias for torch.mul() function and they do the same work. Using either of torch.mul() or torch.multiply() you can do element-wise tensor multiplication between – A scalar and tensor.

The tensor product of two vectors is defined from their decomposition on the bases. More precisely, if are vectors decomposed on their respective bases, then the tensor product of x and y is If arranged into a rectangular array, the coordinate vector of is the outer product of the coordinate vectors of x and y. Vedeți mai multe In mathematics, the tensor product $${\displaystyle V\otimes W}$$ of two vector spaces V and W (over the same field) is a vector space to which is associated a bilinear map $${\displaystyle V\times W\to V\otimes W}$$ that … Vedeți mai multe Given a linear map $${\displaystyle f\colon U\to V,}$$ and a vector space W, the tensor product is the … Vedeți mai multe The tensor product of two modules A and B over a commutative ring R is defined in exactly the same way as the tensor product of vector spaces over a field: More generally, the tensor product can be defined even if the ring is non-commutative. In this case … Vedeți mai multe The tensor product of two vector spaces is a vector space that is defined up to an isomorphism. There are several equivalent ways to define it.

The multiplication of a tensor by a matrix (or by a vector) is called n -mode product. Let T ∈ R I 1 × I 2 × ⋯ × I N be an N -order tensor and M ∈ R J × I n be a matrix. The n -mode product is defined as. ( T × n M) i 1 ⋯ i n − 1 j i n + 1 ⋯ i N = ∑ i n = 1 I n T i 1 i 2 ⋯ i n ⋯ i N M j i n.

Sorted by: 1. Metric tensors are defined as symmetric bilinear forms, so we can write them as symmetric matrices. As general tensors, metric tensors are not commutative in general (try in dimension 2 for example to construct two symmetric matrices that do not commute). Now, if g a b is defined as the inverse matrix of g a b , then g a ...
