dot product一般表示为两个vector点积,结果为标量。 matrix product表示为两个matrix矩阵积,结果为矩阵。 matrix product可以理解为多个dot product; 而dot product也可以理解为一维matrix的matrix product。 https://www.quora.com/What-is-the-difference-between-dot-product-and-matrix-product...
1 Matrix Multiplication 1.1 Basic Algorithms and Notation 1.1.17 The Notion of "Level" and the BLAS level-1 operations: dot product, saxpy level-2 operations: outer product, gaxpy level-3 operations:C=C+AB Important level-1, level-2, and level-3 operations are encapsulated in the "BLAS'...
在DirectXMath.h 头文件中,系统使用对象的别名XMMATRIX,特别是CXMMATRIX。 标头使用 别名来符合不同编译器的最佳内联调用约定。 对于使用 DirectXMath 的大多数项目,只需将其视为 的确切别名XMMATRIX就足够了。 有效: 复制 typedef const XMMATRIX CXMMATRIX; ...

That is, once we define a dot product, then for any scalar function f(x) we can define ∇f by f'(x)[dx]=∇f⋅dx. So ∇f is always something with the same "shape" as x (thesteepest-ascentdirection). Talked about the generalrequirements for an inner product: linearity, posit...
I then claimed that the eigenvectors (properly scaled) are orthonormal, so that F is unitary, but there is a catch: we need togeneralize our definition of "dot"/inner productfor complex vectors and matrices. For complex vectors, the dot product x⋅y isconj(xᵀ)y (conj=complex conjugat...
