Put result in vector

I work on this code and I want to put the result (u) for each (t) into a vector.

function THA(n,E,I,m,L,P0)

vn=1:1:n;%Antal modes

w=1/(2*pi)*vn.^2*pi^2/L^2*(E*I/m)^(1/2); %Egenfrekvens

   % u=C*sin(i*pi*x/L)/i^4*(1-cos(w(i)*t))*sin(i*pi*x/L);

for t=0:0.1:10;

    x=L/2;

   i=1:1:n;

    C=2*P0*L^3/(pi^4*E*I);

    vm=sin(i*pi*x/L);

u=C*sum(vm(i).*1/vn(i).^4*(1-cos(w(i)*t)).*vm);

end

end

Thanks in advance

I don't believe you need to do the above with a for loop, just create a t vector and work with arrays, for example:

t = 0:0.1:10;
vm = sin(2*pi*t);

and then you can use cumsum() in your u.

But if you want to stay with your for loop, then just fill the vector u as you progress through the loop

   u(i) = C*sum(vm(i).*1/vn(i).^4*(1-cos(w(i)*t)).*vm);

Before you enter the for loop, you may want to include the statement

   u = zeros(n,1);

or

   u = zeros(1,n);

to preallocate the vector.
