Multiplying each colum of my matrix by a constant
Posted: Jun 11, 2013 4:59 PM

Hello there,

I'm trouble here, I'm sure that the solution isn't too hard to my problem, but I'm really stucked here and I can't see the light in end of the tunnel right now.

I have matrix 3x3 and a vector 1x3 and I want to multiply each column of my matrix by each element of my vector, for example:

If my matrix 3x3 is called M and my vector v is a 1x3 dimension:
M(:,1) = M(:,1).*v(1);
M(:,2) = M(:,2).*v(2);
M(:,3) = M(:,3).*v(3);

Ofc, I want to avoid use 'for loops'.

Thx.
