How to get function handles from sybolic vector of variables for ode45?

I am trying to solve Xdot=f(X,U). X U are vectors. From symbolic algebra i had derived Xdot.I need to convert this into a suitable function handle for ode45. (dsolve didnt work)

Sandeep, use matlabFunction to convert the ODE from symbolic to numeric. You can then use ode45 to solve the differential equation.
