%I have this function script, created and saved with no mistakes. When I try to solve the ODE, using ode45 it does not work, I get this:
Error using fevalUndefined function 'govequ' for input arguments of type'double'.Error in odearguments (line 87)f0 = feval(ode,t0,y0,args{:}); % ODE15I sets args{1} to
yp0.Error in ode45 (line 113)[neq, tspan, ntspan, next, t0, tfinal, tdir, y0, f0,odeArgs, odeFcn, ...
Here, the function script:
function y_dot = govequ(t,y)y_dot = -t^2-4*y;end
And here the command I use to solve it:
[ts,ys] = ode45(@govequ, [0,10], 1)
