A Matlab loop problem. Getting 1 solution instead of 54. Anyone knows why?

hi there,

I programmed a little script that uses a function to calculate a call price in the heston model. Now I built in a for loop that should calculate the Call price for each day in my excel sheet. There are 54 days, so I consider to get 54 solutions. But I only receive 1 solution. Anyone knows why?

Here is my code:

   daten=xlsread('CallPreise.xlsx','Jan','B2:K55'); %Januar 
    phi = 1; 
    S=daten(:,1); 
    K=daten(:,2); 
    T=daten(:,3); 
    rd=daten(:,4); 
    rf=daten(:,5); 
    kappa=daten(:,6); 
    theta=daten(:,7); 
    sigma=daten(:,8); 
    rho=daten(:,9); 
    v0=daten(:,10); 
    alpha=0.75; 
    method=1; 

    s0 = log(S); 
    k = log(K); 
    ende = length(S); 
    Call = zeros(ende,1); 

     for count = 1:ende 

        Call = HestonFFTVanilla(phi,S(count),K(count),T(count),rd(count),rf(count),kappa(count),... 
               theta(count),sigma(count),rho(count),v0(count),alpha,method); 

     end

Call(count)=HestonFFTVanilla(phi,S(count),K(count),T(count),rd(count),rf(count),kappa(count),... 
            theta(count),sigma(count),rho(count),v0(count),alpha,method);

Best wishes
