5D 向量只有一个轴,沿着轴有 5 个维度,而 5D 张量有 5 个轴(沿着每个轴可能有任意个维度) 矩阵(matrix):是一个按照长方阵列排列的复数或实数集合,矩阵是二维张量(2D 张量) np.array([[5, 78, 2, 34, 0], [6, 79, 3, 35, 1], [7, 80, 4, 36, 2]]) 向量组成的数组叫作矩阵(matrix)或...
In this revised and expanded edition, Dennis Bernstein combines extensive material on scalar and vector mathematics with the latest results in matrix theory to make this the most comprehensive, current, and easy-to-u... (展开全部) 作者简介 ··· Dennis S. Bernstein is professor of aerospace...
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)...

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 ...
We review the dimensional check problem of the high-level programming languages, discuss the existing solutions, and come up with a new solution suited for scientific and engineering computations. Then, we introduce Univec, our C++ library designed to make scalar, vector, and matrix operations using...
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...
