如何在matlab中将每一行与另一个矩阵元素的每一行相乘？

Question

I have such a matrix

m1 = [ 1 2 3; 4 5 6; 1 2 3]
m2 = [ 2 2 2];

and I want to multiply each row of m1 with m2 elementwise .

So result is

result = [2 4 6; 8 10 12; 2 4 6]

How would I do it?

Answer 1

 bsxfun(@times,m1,m2)


ans =

     2     4     6
     8    10    12
     2     4     6

Answer 2

你也可以用

 result = diag(m2)*m1;
