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...
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)...

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)或二维张量(2D 张量)。矩阵有 2 个轴(通常叫作行和列)。你可以将矩阵直观地理解为数字组成的矩形...
A matrix is an array of numbers (one or more rows, one or more columns). In fact a vector is also a matrix! Because a matrix can have just one row or one column. So the rules that work for matrices also work for vectors.Math...

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...
Reduced isospin scalar and vector matrix elements can be extracted from comparison of electromagnetic transitions between analogous states in isospin triplets. Calculations for the transitions between the first 2 +, T = 1 and 0 +, T = 1 levels in the A = 26 triad indicate that only the ...
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 effect of the unitary mixing of scalar and vector fields is considered in the ξ gauge. For this effect to emerge, it is necessary that the vector current not be conserved; in the ξ gauge, there arise additional complications because of the presence of an unphysical scalar field. Solut...
