scalar value
1Scalar (computing) — In computing, a scalar is a variable or field that can hold only one value at a time; as opposed to composite variables like array, list, record, etc. In some contexts, a scalar value may be understood to be numeric. A scalar data type is the… …
2Scalar field — In mathematics and physics, a scalar field associates a scalar value, which can be either mathematical in definition, or physical, to every point in space. Scalar fields are often used in physics, for instance to indicate the temperature… …
3scalar field — noun A function that assigns a scalar value to every point in space. See Also: vector field …
4Scalar theories of gravitation — are field theories of gravitation in which the gravitational field is described using a scalar field, which is required to satisfy some field equation. Note: This article focuses on relativistic classical field theories of gravitation. The best… …
5Scalar programming — is a term used to refer to those programming approaches that do not follow the array programming paradigm. The fundamental idea behind scalar programming is that operations apply to a single value at a time. This makes it a low level programming… …
6Scalar field theory — In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A field which is invariant under any Lorentz transformation is called a scalar , in contrast to a vector or tensor field. The quanta of the… …
7Scalar (mathematics) — In linear algebra, real numbers are called scalars and relate to vectors in a vector space through the operation of scalar multiplication, in which a vector can be multiplied by a number to produce another vector.More generally, the scalars… …
8Scalar curvature — In Riemannian geometry, the scalar curvature (or Ricci scalar) is the simplest curvature invariant of a Riemannian manifold. To each point on a Riemannian manifold, it assigns a single real number determined by the intrinsic geometry of the… …
9Scalar (physics) — In physics, a scalar is a simple physical quantity that is not changed by coordinate system rotations or translations (in Newtonian mechanics), or by Lorentz transformations or space time translations (in relativity). (Contrast to… …
10Scalar — A scalar is a variable that only has magnitude, e.g. a speed of 40 km/h. Compare it with vector, a quantity comprising both magnitude and direction, e.g. a velocity of 40km/h north .* Scalar (mathematics), a quantity which is independent of… …
