## What is a tensor? |

A tensor is a quantity that depends linearly on many vector variables. They are considered to be a set of *n*' components that are functions of the coordinates at any point in *n* dimensional space. Tensors are used in several fields of mathematics, such as the theory of elasticity (stress and strain) and mathematical physics, especially with regard to the theory of relativity.
