My matlab code is only returning first output

So my code here is only returning the first ouput voltage and is also saving it as ans in workshop instead of voltage, I want it to return all three outputs by their name and save them into workshop but I can't figure out what's wrong?

function [voltage, current, evarde] = kretsen2;

U0 = 220;

U = U0;

I0 = 0;

I = I0;

u0 = [I0;U0];

u = u0;

C = 0.5*(10^-6);

L0 = 0.7;

t = 2*pi*sqrt(L0*C);

%t = 0.01;

f = @(t,u) [u(2)/(L0*((1^2/(u(1)^2+1^2))));-u(1)/C];

n = 1000

h = t/n;

listX = 0

listY = u'

for x = 0:h:t-h

k1 = f(x,u);

k2 = f((x+h)/2,u + (h/2)*k1);

k3 = f((x+h)/2,u + (h/2)*k2);

k4 = f(x+h,u + h*k3);

u = u + (h/6)*(k1+2*k2+2*k3+k4);

listX = [listX;x];

listY = [listY;u'];

end

current = listY(:,1);

voltage = listY(:,2);

evarde = (1/2)*C*voltage.^2 + (1/2)*L0*log(1+current.^2);

figure

plot(listX,current)

title("current")

figure

plot(listX,voltage)

title("voltage")

figure

plot(listX,evarde)

title("E(t)")

end

You need to call the function with all three outputs, e.g.:

[Vout, Iout, E] = kretsen2();

Very basic MATLAB concepts, such as how to call functions with multiple output arguments, are explained in the introductory tutorials:

That's exactly what I did though...

"That's exactly what I did though"

Did it work then? If not, please explain how you are checking if the variables are that workspace.
