Why is my For loop only using the last input number

Hi I have a question on why my For loop is only using the last number (n = 7) and not using the values when n = 1-6. Below is my For Loop that is in my main script, and the actions of the For loop is part of my main function. The picture attached is the trajectory of each basketball shot; I'm suppose to be having 7 trajectories, but the For Loop only reads the last input. Please help and Thanks in advance.

for n = 1:7
       [Xo, Yo, Zo, Imag, theta, phi, omgX, omgY, omgZ] = read_input('A.data',n);
          [T, X, Y, Z, U, V, W] = basketball( Xo, Yo, Zo, Imag, theta, phi, omgX, omgY, omgZ);

        end

        figure(1); hold on;
        plot3(X,Y,Z)

Write the plot command inside the loop.

    figure(1); 
  for n = 1:7
         [Xo, Yo, Zo, Imag, theta, phi, omgX, omgY, omgZ] = read_input('A.data',n);
            [T, X, Y, Z, U, V, W] = basketball( Xo, Yo, Zo, Imag, theta, phi, omgX, omgY, omgZ);
             plot3(X,Y,Z)
             hold on
  end

clear X Y Z
for n = 1:7
  [Xo, Yo, Zo, Imag, theta, phi, omgX, omgY, omgZ] = read_input('A.data',n);
  [T, X(:,n), Y(:.n), Z(:,n), U, V, W] = basketball( Xo, Yo, Zo, Imag, theta, phi, omgX, omgY, omgZ);
end

Note: this code assumes that all of the trajectories have the same length for X, Y, and Z
