1、乘积 用于矩阵相乘，表示为C=A*B，A的列数与B的行数必须相同，C也是矩阵，C的行数等于A的行数，C的列数等于B的列数。Cij为A的第i行与B的第j列的点积。2、点积 用于向量相乘，表示为C=A.*B，A与B均为向量，C为标量，也称标量积、内积、数量积等。数量积(dot product; scalar product...

在数学中,矩阵(Matrix)是一个按照长方阵列排列的复数或实数集合,最早来自于方程组的系数及常数所构成的方阵,这一概念由19世纪英国数学家凯里首先提出。 何谓矩阵就是输入的数据就是矩阵,对数据做任何的操作都是矩阵的操作。 定义:矩阵是由行和列组成的,即 m*n 个数 aij 排成 m 行 n 列 的表格称为矩阵,简...
