clc; clear all; close all;
y0=1;
tSpan=[0 10];
[t,y]=ode45(@(t,y) mas(t,y), tSpan, y0);
plot(t,y)
function dt = mas(t,y)
dt=-2*y-t;
end

Hey can anyone please help, i tried using ode45 for a simple function, but i always get the error message:

Error using ode45

Too many input arguments.

Error in programstart (line 8)

[t,y]=ode45(@(t,y) mas(t,y), tSpan, y0);

Why is this?

thanks in advance
