我有以下脚本：
h=[0.01 0.05 0.1 0.5 1];
func = @(t, y) -2*y+t*sin(t);
opts = odeset('Reltol',1e-13,'AbsTol',1e-14,'Stats','on');
f1_f2_matrix = [];
sinus=@(t) t*(sin(t));
error2nd = zeros(length(h),1);
errorInf = zeros(length(h),1);
error2ndEuler = zeros(length(h),1);
errorInfEuler = zeros(length(h),1);
for i=1:length(h)
t=0:h(i):10;
euler = zeros(length(t),1);
fun_builtin = zeros(length(t),1);
t_builtin = zeros(length(t),1);
results = zeros(length(t),1);
%matrix for A=-2 and given h=0.01
matrix=[ 1-1/2*h(i), (1/2-sqrt(3)/3)*h(i);
(1/2+sqrt(3)/3)*h(i), 1-1/2*h(i)];
for n=2:length(t)
B = [-2*results(n-1) + sinus(t(n-1)+(1/2-sqrt(3)/6)*h(i));
-2*results(n-1) + sinus(t(n-1) + (1/2+sqrt(3)/6)*h(i))];
%system of equations solution
f1_f2_matrix = matrix\B;
results(n) = (results(n-1) + h(i)*0.5*(f1_f2_matrix(1) + f1_f2_matrix(2)));
%euler
euler(n) = euler(n-1)+h(i)*func(t(n-1),euler(n-1));
end
%ode45
[t_builtin,fun_builtin] = ode45(func, t, 0, opts);
%y'=-2y+tsin(t) errors
error2nd(i)=norm(fun_builtin-results)/norm(fun_builtin); %root mean square error of my function
errorInf(i)=norm((fun_builtin-results), Inf)/ norm((fun_builtin), Inf); %maximum error of my function
error2ndEuler(i)=norm(euler-results)/norm(fun_builtin); %root mean square error of my function (euler)
errorInfEuler(i)=norm((euler-results), Inf)/ norm((fun_builtin), Inf);
%maximum error of my function (euler)
end
figure

请考虑上述代码块中的以下行：
%ode45
[t_builtin,fun_builtin] = ode45(func, t, 0, opts);
如果我将其更改为ode113等ode23，则会生成该图形，但是当我将其更改ode45为时出现错误：
Error using ode45
Too many input arguments.
Error in task1 (line 41)
[t_builtin,fun_builtin] = ode45(func, t, 0, opts);
我可以进行哪些更改以使其完美运行？
