Need to do ode45 for various values iteratively

Hi i am writing a code for ode45 for which i have to variate the value of "aplha",after each time the ode45 evaluates and the use the next value. Say i have to use alpha=10:15

function xp=check(t,x)

     xp=zeros(2,1);
          xp(1)=x(2);
          xp(2)=alpha*x(2)-x(1);
  end

running in another m-file

[T,Y]=ode45(@check,[0 0.28],[0.087 0]);
plot(T,Y(:,1),'-o')
grid on;

i need the plot of all in the iteration in a same plot,please help me Thanks

Muahmmad, you are almost there. Use a loop and something like

 function myode()
 alpha = 10:15;
 figure
 hold all
 for ii = 1:numel(alpha)
    [T,Y] = ode45(@check,[0 0.28],[0.087 0],[],alpha(ii));
    plot(T,Y(:,1),'-o')
 end
 hold off
 grid on;
 end

 function xp = check(t,x,alpha)
 xp = zeros(2,1);
 xp(1) = x(2);
 xp(2) = alpha*x(2) - x(1);
 end
