ODE45 Function Error

I have 3 functions. The function rhs.m should compute the function Dynamics.m and Kinematics.m. Later the main.m will execute the ODE45. I set the variable to be 7x1 matrix. I wrote this way Kinematics x(1:4) and Dynamics x(5:7) . Unfortunately I received this error. Any thought on this how to solve it?

Error in odearguments (line 90)
f0 = feval(ode,t0,y0,args{:});   % ODE15I sets args{1} to yp0.

Error in ode45 (line 115)
  odearguments(FcnHandlesUsed, solver_name, ode, tspan, y0, options, varargin);

Error in main (line 9)
[t,x]=ode45(@rhs,t,x0);

Where are input arguments for functions?

dq=(Kinematics);
dw=(Dynamics);

Thanks! You correct my noob mistake!

dq = Kinematics(qib, bw);
dw = Dynamics(bw, itaud, bI);
