input symbolic parameters in ode45

I want to solve symbolically an ODE using ode45. The equation is:

function dydt = findbk(t,y)
    J1 = 0.2;
    T0 = 0.1;
    J2 = 0.1;
    theta1ddot =  k/J1 * (y(2) - y(1));
    theta2ddot = T0/J2 - b*y(4)/J2 - (k/J2)*(y(2)-y(1));
    dydt = [y(3);y(4);theta1ddot;theta2ddot];
end

Is there a way to input symbolically b and k and use:

[t,y] = ode45(@findbk,[0:0.01:10],[0,0,0,0],options);

To solve the ode?

ODE45 integrates numerically. It does not offer a symbolic solution.
