In mathematics and physics, a tensor is a mathematical object that describes a geometric relationship between vectors, scalars, and other tensors. A tensor can be thought of as a generalization of vectors and matrices to higher dimensions, and it is often used to describe the physical properties of a system, such as its stress, strain, or electromagnetic field.

Tensors have multiple components that are arranged in a particular way, and they transform under certain rules when one changes the coordinate system. The order of a tensor is the number of indices needed to specify each of its components, and tensors of different orders have different transformation properties.

Tensors are widely used in various fields of physics and engineering, such as relativity, electromagnetism, fluid mechanics, and solid mechanics. They are also used in machine learning and deep learning, where they are used to represent and manipulate multi-dimensional data structures, such as images or time series.
