I am looking for a way to multiply one row values with every row values.
Let's assume we have:
A=[1 2 3;
4 5 6;
7 8 9]
B=[a b c]
I am looking for a way to have:
C=[1*a 2*b 3*c;
4*a 5*b 6*c;
7*a 8*b 9*c]
Thanks in advance for your comments.
NB : bsxfun working fine on my version. But, It is showing correct calculations when I have a small row numbers. But, when I have a very large row numbers (say, 10,00000) then it's showing me wrong calculations..
Is there other ways you can help me..?

I didn't calculated million rows manually. I just calculated first 8/10 rows and saw that the value i expect is not equal to the value i am getting from the MATLAB Calculations. I think, you got my point.
