Definition. Mathematically a scalar field on a region U is a real or complex-valued function or distribution on U. The region U may be a set in some Euclidean space Minkowski space or more generally a subset of a manifold and it is typical in mathematics to impose further conditions on the field such that it be continuous or Vector calculus or vector analysis is a branch of mathematics concerned with differentiation and integration of vector fields primarily in 3-dimensional Euclidean space.

Scalar definition representable by position on a scale or line having only magnitude a scalar variable.

A vector is a single dimension (1D) tensor which you will more commonly hear referred to in computer science as an array. An vector is made up of a series of numbers has 1 axis and is of rank 1.

(Arfken 1985 p. 159). Tensor notation can provide a very concise way of writing vector and more general identities. For example in tensor notation the dot Note that is not a usual polar vector but has slightly different transformation properties and is therefore a so-called pseudovector (Arfken 1985 pp. 22-23). Jeffreys and Jeffreys (1988) use the notation to denote the cross product.Basic Tensor Functionality. Theano supports any kind of Python object but its focus is support for symbolic matrix expressions. When you typeVector analysis Vector analysis a branch of mathematics that deals with quantities that have both magnitude and direction. Some physical and geometric quantities called scalars can be fully defined by specifying their magnitude in suitable units of measure.
