The tensor product of elements in these vector spaces that one usually sees in engineering and physics texts (frequently matrices) is basically an element in the tensor product of the corresponding vector …

A k k -tensor is a multilinear function from V × V × ⋯ × V V × V × × V to the reals, where V V is a vector space and k k is the number of the V V 's in the above Cartesian product. (Calculus on Manifolds, …

2015年2月5日 · Tensor : Multidimensional array :: Linear transformation : Matrix. The short of it is, tensors and multidimensional arrays are different types of object; the first is a type of function, the …

2024年12月8日 · We call that an operator is (n, m) (n, m) tensor (or tensor field) if it is a linear operators that takes m m vectors and gives n n vectors. Conventionally, 0 0 -vectors is just a scalar.

2013年6月6日 · What is the difference between a matrix and a tensor? Or, what makes a tensor, a tensor? I know that a matrix is a table of values, right? But, a tensor?

2024年2月11日 · A tensor extends the notion of a matrix analogous to how a vector extends the notion of a scalar and a matrix extends the notion of a vector. A tensor can have any number of dimensions, …

tensor - In new latin tensor means "that which stretches". The mathematical object is so named because an early application of tensors was the study of materials stretching under tension.

2007年5月10日 · A rank 3 tensor is defined as a multi-linear function that takes three generalized vectors as input and outputs a scalar. It can also take two generalized vectors (or a rank 2 tensor) …
