WebApr 26, 2024 · In this video we introduce the notion of a vector field, how it differs from a scalar field, and how to plot a basic 2D field by hand. WebSuch a function describes a vector ﬁeld. Thus, by taking the gradient we convert a scalar ﬁeld to a vector ﬁeld. If a vector ﬁeld F can be written in the form ∇f for some scalar ﬁeld f, then we call F a gradient ﬁeld, or a conservative ﬁeld. The identity df/dt = ∇f · v is about a function in variable t. Thus ∇f should be

WebJul 25, 2024 · A scalar field has a value associated to each point in space. Examples of scalar fields are height, temperature or pressure maps. In a two-dimensional field, the value at each point can be thought of as a height of a surface embedded in three dimensions. 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 often continuously differentiable to some order. A scalar field is a tensor field of order zero, and the term "scalar field" may be used to distinguish a function of this kind with a m…
