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...
Note that it should not be confused with the more common matrix product. Tensor product. Given two vectors, this product takes each element of a vector and multiplies it by all of the elements in the other vector creating a new row in the resultant matrix. Let N and M are two vectors ...
Please keep reading to learn the dot product formula our calculator uses, how to estimate the dot product of two vectors, and how to generalize the formula for the matrix dot product. Together with the cross product calculator, you'll learn that vector algebra isn't anything to worry about!
Explanation:First, Declare the first input matrix. Declaring the second input matrix. Passing the input matrices to the dot function. * Mathematically, the dot product of matrix [3 5 3 6;4 1 6 0;7 3 9 2] and [1 0 3 5;4 3 6 1;7 1 3 0] is (68 6 72 30), As we can se...
