Let f be a scalar field and F a vector field. State whether each expression is meaningful. If not, explain why. If so, state whether it is a scalar field or a vector field.(grad\ f)* (div\ F) 相关知识点: 试题来源: 解析 (grad\ f)* (div\ F) is meaningless because div F...
This paper describes a general-purpose algorithm for computing the gradients in space and time of a scalar field, a vector field, or a divergence-free vector field, from in situ measurements by one or more spacecraft. The algorithm provides total error estimates on the computed gradient, ...

A numerical simulation has been developed to investigate the random focusing for an acoustic plane wave propagating through scalar or vectorial turbulent fields. The turbulence is represented as a set of realizations of random fields (temperature or incompressible velocity) generated by a limited number...

Vector functions: The vector function (aka a vector field) is a function which returns a vector at each location of space. Examples include the gravitational field (at each location we have a different vector defining the local acceleration of gravity), the electric field, the velocity field of...
vector field or Vector-valued procedure; specify the components of the vector field Description • The ScalarPotential(v) calling sequence computes the scalar potential of the vector field v. This is a function f such that Gradientf=v. If a scalar potential does not exist, NULL is...
