ODE45 ERROR en el @odefun

Hola!
Estoy utilizando el comando ODE45 para resolver una ecuación diferencial pero me da erro en la función que utilizo para el ODE45,
Me aparecen los siguientes errores, ¿a que se refiere con ''Index exceeds matrix dimensions''?.
clear all
clc
tspan=[0:0.1:10]
CI=[0 0]
[t Y]= ode45(@resode,tspan,CI)
plot(tspan,Y(:,1),'-','b')
hold on
grid on
plot (tspan,Y(:,2),'.','g')
La función es:
function dfidt=resode(t,fi)
delta1 = pi/12*sin(pi*t/3);
delta2 = 0 ;
delta3 = -pi/12* sin((t-4)*0.5*pi);
delta4 = 0 ;
Delta=((t>0)&(t<=3)).*delta1 + ((t>3)&(t<=4)).*delta2 + ((t>4)&(t<=6)).*delta3 + (t>6).*delta4;
Ix=3783.5
Mfip=3481.2
Mfipp=1196
Mdel=1334.2
fi1=fi(1)
fi2=fi(2)
dfi1=fi(2)
dfi2=-Mfip*fi2/(Ix-Mfipp)+Mdel*Delta/(Ix-Mfipp)
dfidt=[dfi1(1);dfi2(2)]
end
