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...
An integrated circuit ( 102 ) and method computes fixed point vector dot products ( 424 ) and/or matrix vector products using a type of distributed architecture that loads bit planes (add 00 -add 30 ) and uses the loaded bit planes to generate a plurality of partial products ( 416 - ...
在numpy中,一重方括号表示的是向量vector,vector没有行列的概念。二重方括号表示矩阵matrix,有行列。 代码显示如下: import numpy as np a=np.array([1,2,3]) a.shape #(3,) b=np.array([[1,2,3],[3,4,5]]) b.shape #(2, 3) c=np.array([[1],[2],[3]]) c.shape #(3, 1) 即使...
