Hallo guys,
How can i multiply rows of two different arrays in a for loop?
So my starting point is a 4x8 (A) matrix and a 4x1 (B) matrix and I want to multiply point A(1x1) with B(1x1), A(2x1) and B(2x1) ... A(1x2) and B(1x1) etc.
I tried this: Mw(4x8) and m(4x1)
Steigung1_neu = zeros(1,8);
startWert = (1);
endWert = (8);
N1 = 1;
for index = startWert:1:endWert
Steigung1_neu(N1) = Mw(2,index)/m(2);
N1 = N1 +1;
end
This just multiplys every row, but I want to multiply every colum.
Would be nice, if you guys can give some tipps.

In the code above, you don't do anything that has to do with the question.

A = rand(4,8) ;
B = rand(4,1) ;
iwant = A.*B ;

What does "the pointer goes the wrong way" mean?
KSSV's answer solves: "multiply point A(1x1) with B(1x1), A(2x1) and B(2x1) ... A(1x2) and B(1x1) etc."
