It takes two vectors and returns a number. And it’s linear in each argument. Suppose you have vectors u, v, and w, and a real number a. Then the dot product (u + v, w) equals (u, w) + (v, w) and (au, w) = a(u, w). This shows that dot product is linear in its...

As per the wiki definition of Tensors: Tensors are geometric objects that describe linear relations between geometric vectors, scalars, and other tensors. Elementary examples of such relations include the dot product, the cross product, and linear maps. Geometric vectors, often used in physics and...
The CPD decomposes a tensor T into the sum of R outer products of vectors. Formally, for a third-order tensor: R T ≈ ar ◦ br ◦ cr r =1 (2) We can then attempt to iteratively minimize the Frobenius norm of the error: T− R r =1 ar ◦ br ◦ cr . A common ...
Tensors are the natural generalisation of vectors and matrices. A tensor of rank r is defined as an element \(d_1 \times \cdots \times d_r\) existing in the space \(\mathbb {C}^{d_1,\cdots ,d_r}\). Thus a vector with d complex elements (dimension d) can be considered as...
where ∘ represent the outer product of two vectors. is the rth column vector of the decomposed factor matrix and is a rank-one tensor. R is the CP rank of the tensor . Correspondingly, the element in the tensor is written as follows: (2) where is the element with an index of ...
instead a sliceT%abcd(1:i_max,1:j_max,1:k_max,1:l_max)is returned. This can be useful when dealing with mixed formulation or variation principles where the last entry/entries of stress and strain voigt vectors are used for the pressure boundary. To export a full stress tensorS1to vo...
