A tensor is an abstract object generalising a scalar or vector and can be represented by a number, a 1D array, 2D matrix or higher order generalisations thereof. A tensor product is a product defined on these tensors yielding other tensors or a method to define or represent tensors. If appropriate, also use the [mathematics] tag.

## What are tensors?

A tensors is an $\left(n, m\right)$-order structure that generalizes scalars and vectors to higher orders and can be represented by a number, array, matrix, or higher order generalisations thereof. In physics, tensors with a 3- or 4- dimensions are common, but higher dimensions are sometimes used. For a formal definition, consult the standard sources, e.g. Wikipedia.
