Element wise multiplication of every row/column of a matrix with a vector

Question

I have a matrix, named as p_c_w having dimensions 6X7599 and the other matrix named as p_w having dimensions 1X7599. I wish to have their element-wise multiplication but I a

Answer 1

From R2016b release, you do not need to use bsxfun for this operation. For example, the following code will do the same thing as @thewaywewalk's answer.

A = [ 1 2 3 4 5;
      1 2 3 4 5;
      1 2 3 4 5 ];

B = [ 1 10 100 1000 10000];

C = A.*B

Check out doc for implicit expansions.

Answer 2

use bsxfun:

A = [ 1 2 3 4 5;
      1 2 3 4 5;
      1 2 3 4 5 ];

B = [ 1 10 100 1000 10000];

C = bsxfun(@times,A,B)  

returns:

C =

           1          20         300        4000       50000
           1          20         300        4000       50000
           1          20         300        4000       50000

Works the same for A' with B'

so for your case:

temp = bsxfun(@times,p_c_w,p_w)
