A tensor is a mathematical object that extends the notion of scalars, vectors, and matrices in a regular mathematical space of any dimension. Scalars are 0-dimensional objects that carry a single value, such as 2 or pi. Vectors are one-dimensional arrays of scalars and represent entities with both magnitude and direction. Matrices are two-dimensional arrays of scalars and are used to provide further geometric transformations through multiplication. Higher dimensional arrays of scalars are called tensors and are represented in a multidimensional Euclidean space.
