Scalar and vector fields arise naturally in a variety of physical situations. For example, when a gas flows along a pipe there are associated with any point in the pipe the gas pressure p , the density 蟻, and th
数量场与向量场( Scalar fields and vector fields) 物理量通常都由其空间位置和时间确定,物理量在空间或空间-时间的分布称为这个物理量的场(field). 如果物理 量是数量,称为数量场(Scalar field). 如果物理量是向量,称为向量场(Vector field). 例如大气中的温度分布是 数量场,大气流动时的速度分布是向量场[...
Such fields play an important role in environmental fluid mechanics. Finally, notice that a linear vector field has a constant divergence, but in general the divergence varies in space, as shown in the following example. Example 2.2.2 Consider the vector field shown in Fig. 2.4A. The pattern...
I have a scalar struct S with each field a row vector of the same number of elements. 테마복사 S.x = [1 2]; S.y = [10 20]; I want create a struct array, A, with same number of elements as in the fields in S, with the same field na...
to verify that we always have the result\(\zeta \simeq \kappa _1\)for anisotropic power-law solutions, regardless of the nature of scalar fields as well as the number of scalar and vector fields counted in the KSW model. The reason is based on the fact that we can always defineuand...
