Hey guys is it possible to write a 'for' loop for my code?

My code looks like this

    l=[6 7 8 9 10 11 12]'; %cord length 

    r=(l/Ltest)';  %ratio between lengths and test length(0.75)

    % deflection of each cord

    l1=(r(:,1)*x);   

    l2=(r(:,2)*x);

    l3=(r(:,3)*x);

    l4=(r(:,4)*x); 

    l5=(r(:,5)*x); 

    l6=(r(:,6)*x); 

    l7=(r(:,7)*x);

'x' is a 243 by 1 matrix

Can this code be made much simpler with using a 'for' loop?

Ive only begun to use matlab recently and would greatly appreciate your help.

out = x(:) * l(:)'/Ltest;

>> vec = [6,7,8,9,10,11,12];
>> Ltest = 0.75;
>> x = randi(9,342,1);
>> R = vec / Ltest;
>> out = x * R;
