MATLAB: Can somebody help me with: “Error in odearguments (line 90)” and “Error in ode45 (line 115)”

ode45 (line 115) and odearguments (line 90)

Hello all together,
I have written the following code:
function Solve_Feder_2 (w, d, s, tm)
% Anfangswerte
y0 = [s,0];
% Zeitintervall
tspan = [0, tm]; 
% Lösung des Anfangswertproblems
[t,y] = ode45 ( @Fun_Feder_2, tspan, y0, [], w*w, d);
z = y (:,1); % daraus den Funktionswert = 1. Komponente
% plotten
plot (t, z);
grid on;__
And I am receiving the following errors:
>> Solve_Feder_2 (10,1,1,2)
Attempt to execute SCRIPT Fun_Feder_2 as a function:
C:\Users\Heisele\1mpd\Studium\Fächer\Orientierungsstudienprojekt\OSP II\Dgl tests\Fun_Feder_2.m
Error in odearguments (line 90)
f0 = feval(ode,t0,y0,args{:});   % ODE15I sets args{1} to yp0.
Error in ode45 (line 115)
    odearguments(FcnHandlesUsed, solver_name, ode, tspan, y0, options, varargin);
Error in Solve_Feder_2 (line 8)
[t,y] = ode45 ( @Fun_Feder_2, tspan, y0, [], w*w, d);
Can somebody help me? Thanks in advance and best regards Uli
