How to save values in vector for multiple loops?

Hi, so I am writing this code and it uses two for loops. I'm writing a simplified version of the code here..

n=2;
m=3;
k=[1; 2];
for i=1:n
    for j=1:m
        kk=k(i);
        l=j*kk;
    end 
end

I need to save values for both k=1 and k=2; but it ends up saving values for only the last iteration i.e k=2. The result should be a 3x2 matrix but its a 3x1 matrix..

Thanks in advance!

Maybe this if you want a 3x2 result (but l is a really lousy name for a variable):

n=2;
m=3;
k=[1; 2];
l = zeros(m,n);
for i=1:n
    for j=1:m
        kk=k(i);
        l(j,i)=j*kk;
    end 
end

Thanks, I figured it out.. but I'm running into trouble trying to do a surface plot now.. Would you know how I should do that?

How about using surf()?????

yeah i was using it. But I wanted to use m not equal to n and it wasn't working out...
