My matlab code is only returning first output
显示 更早的评论
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"
Did it work then? If not, please explain how you are checking if the variables are that workspace.
