I keep getting this error when I initialize my function,
function dy = pendode2(t,y)
dy= zeros(2,1); % a column vector
A=110;
B=0.01;
C=0.001;
g=9.81;
L = (3*g)/(2*A);
omega=0.002;
% E=0.00011;
E=0.2;
d=80e-3;
h= d+(L*(1-cos(y(2))));
r= ((L*sin(y(2)))^2+(h)^2)^0.5;
dy(1)=A*sin(y(2))+B*sin(omega*t)-C*y(1)+cross( ((abs(y(2))/y(2)))*(E/r),cos( abs(y(2))+atan(-abs(h/L*sin(y(2))))));
dy(2)= y(1);
end
The error is as follows, "Error using pendode2 (line 13) Not enough input arguments."
where line 13 is, "h= d+(L*(1-cos(y(2))));"
I do not understand what's wrong with this line!
Furthermore, in another editor window,
options=odeset('RelTol',2.22045e-14,'AbsTol',[1e-14 1e-14]);
[t,y]=ode113(@pendode2, [0 1000], [0 0.2], options);
z1=diff(y(:,1));
z2=diff(y(:,2));
end
Returns an error:
Error in Simulator1 (line 2) [t,y]=ode113(@pendode2, [0 1000], [0 0.2], options);
PLEASE HELP.

There is nothing wrong with this line. If you call the function correctly:
res = pendode2(5,[1 1])
you get the cross product error like in the same question you already asked.
