A tensor is a mathematical object of a multi-dimensional space making changes of reference frame possible.

Tensors are used in differential geometry and mechanics (stress tensor, inertia tensor) and in relativity.

Mathematics A tensor is generally a function of the coordinates of space defined in an n-dimensional space by nk components where k is the order of the tensor.

In three-dimensional Euclidean space, a tensor of order zero is a scalar, a tensor of order one is a vector and a tensor of order 2 is a matrix.
