Example: multiply the vector (5,2) by the scalar 3 a = 3(5,2) = (3×5,3×2) = (15,6) It still points in the same direction, but is 3 times longer(And now you know why numbers are called "scalars", because they "scale" the vector up or down.)...
张量(Tensor)、标量(scalar)、向量(vector)、矩阵(matrix) 张量(Tensor):Tensor = multi-dimensional array of numbers 张量是一个多维数组,它是标量,向量,矩阵的高维扩展 ,是一个数据容器,张量是矩阵向任意维度的推广 注意,张量的维度(dimension)通常叫作轴(axis), 张量轴的个数也叫作阶(rank)] 标量(scalar)...
1.标量(Scalar)数值量。 2.向量(Vector)数值量加方向,数值表示每个维度上的量,而 1 维数组的项数表示空间维度数。 3.矩阵(Matrix)数值量加方向,数值表示每个维度上的量,而 2 维数来表示空间维度数。 4.张量(Tensor)抽象表达的不是维度而是维度的等级。比如标量

Matrix-Muckenhoupt weightsspace--filing curveWe inspect the relationship between the JA.p,q condition for families of norms on vector valued functions and the Ap condition for scalar weights. In particular, we will show if we are considering a norm-valued function ρ(.) such that, uniformly ...

The resulting transition matrix elements for the 2 + 1 → 0 + 1 and 2 + 2 → 0 + 1 transitions are compared with those for the analogue transitions in 34S ( T z = + 1) and 34Cl( T z = 0) to determine the isoscalar and isovector components. The component values are compared...
The leading-order equations of the $1/N$ -- expansion for a vector-matrix model with interaction $g\\\phi_a^*\\\phi_b\\\chi_{ab}$ in four dimensions are investigated. This investigation shows a change of the asymptotic behavior in the deep Euclidean region in a vicinity of a certain...
