how to print the result of for loops in two column

Hi

I have these two for loops and i want to print them in two column but it prints in one column how can I change my code that i have two column

qd(1,:) = Ftu(1).*qu(1)

for i = 2:10
    qd(i,:) = (1 - Ftu(i))*qd(i - 1,:) + Ftu(i).*qu(i);
    if i == 10
        for k = 11:20
            qd(k,:) = (1 - Ftu(k))*qd(10,:) + Ftu(k).*qu(k);
        end
    end
end

and it is my answer

[Walter Roberson]

qd(1,:) = Ftu(1).*qu(1)

if qd does not exist here then it will be created with one column because the right hand side is scalar.

You never assign a second column, and we cannot tell what you want to store there

Although we can't tell, maybe qu is a 2-column array and just missing the colon there???

qd(1,:) = Ftu(1).*qu(1,:);

MIGHT do the trick, but as Walter says, we can't know, can only guess, ...

The above code (without addressing the two-column issue) could be written with MATLAB vector addressing as

qd(1,:) = Ftu(1).*qu(1)
i=(2:10);
qd(i,:) = (1 - Ftu(i)).*qd(i-1,:) + Ftu(i).*qu(i);
k=(11:20);
qd(k,:) = (1 - Ftu(k)).*qd(10,:) + Ftu(k).*qu(k);
