Ifxis a matrix, define the Jacobian ofF(x) by changing the matrixxto a vector, column by column. For example, if X=[x11x21x12x22], then the gradient is defined in terms of the vector x=⎡⎢⎢⎢⎢⎣x11x21x12x22⎤⎥⎥⎥⎥⎦. ...
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网格。下面是一个 Numpy 矩阵。 3D 张量与n 维张量将多个矩阵组合成一个新的数组,可以得到一个 3D 张量,你可以将其直观地理解为数字组成的立方体。下面是一个 Numpy 的 3D 张量...
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...

2.3.1 Matrix-Vector Multiplications Multiplication of Ĥ by trial vectors is required by diagonalization procedures that are appropriate for large matrices. Storage of the 2hp-2hp and 2ph-2ph blocks in memory [9, 32] or on external disks is impractical here, especially for low-symmetry molecul...
