How to make faster row-wise Matrix multiplication ?

Hi All,

I want to make my code run faster. I have to do row wise multiplication. But i do not want to use for loop.

For example

A =
    11    11     6
     7    11     9
     2     2     2
     4    11     5
     7    11    11
B =
     1     2     3
     1     4     3
     1     2     5
For i:1:5
    A(i,:).*B
End

I want to skip the last for loop. As number of rows of A can grow upto 10,000

Any suggestion how to replace or make the code faster instead of using parfor?

Just use:

out = permute(A,[3,2,1]).*B;
