上图中,矢量n为平面的normal vector(法线的矢量),a为平面上已知点的position vector,r为平面上任意一点的position vector(可理解为整个平面)。从几何学我们知道,法线垂直于平面上任意一条直线,所以法线和平面上任意一条直线的点乘为0(点乘dot product,dot product也可以叫做scalar product)。我们用两个posit
Summary This paper is concerned with computational algorithms for estimating the propagation parameters of a plane seismic wave using data from a small-aperture three-component seismic array. This problem is treated as a statistical one involving nuisance parameters arising from a significantly correlated...

The vector equation of a plane is given by, (r-a).n=0, where a is the position vector of a point on plane and n is the normal vector.Hence, the vector equation is (r- i- j ).(-6 i+6 j+6 k)=0 or r.(-6 i+6 j+6 k)=0 or r.(- i+ j+ k)=0.We have to ...
The space X of all functions represented by vector valued Dirichlet series and analytic in a half plane is considered in this paper. The space is en-dowed with a certain topology under which X become a Frechet space. On this space the fo... GS Srivastava,A Sharma - 《International Journa...
Paraxial light too is vectorial, in two dimensions, characterized by an inhomogeneous polarization structure across the transverse plane9. Vectorial structured light in two and three dimensions has been instrumental in a range of applications10,11,12,13, for example, to drive currents with a ...

In this explainer, we will learn how to convert between rectangular and polar forms of a vector. When we think about vectors in the plane, we usually think of Cartesian coordinates as this is the most prevalent coordinate system, which leads to the rectangular form of a vector. In particular...
Thenumerical divergenceof a vector field is a way to estimate the values of the divergence using the known values of the vector field at certain points. For a 3-D vector field of three variablesF(x,y,z)=Fx(x,y,z) ˆex+Fy(x,y,z) ˆey+Fz(x,y,z) ˆez, the definit...
As a phase retrieval method, the desired phase distribution obtained with the GS algorithm is calculated by constructing an iterative loop between the object plane and the hologram via a Fourier transform37. Crucially, the phase φ3 has a quantified relation with both other phases φ1 and φ2,...
