Hello,
I am trying to solve this simple system:
freq = 100000;
epsilon = 1119.2;
sigma = 0.00045128;
syms x y
eq1=x-1i*y==1119.2;
eq2=(2*pi*freq*y+sigma)/(2*pi*freq*x)==0.07248;
eqns=[eq1 eq2];
S=solve(eqns, [x,y]);
I keep getting the error:
One or more output arguments not assigned during call to "varargout".
I have ran out of options on trouble shooting this. It is a system of two equations and two unknowns written exactly like the example for the solve function. Any ideas?

You should be using vpasolve() not solve()

No coding error in any case

Hi,
Your code's problem is that you are using this code inside your function file. Here is the corrected code:
function Solution = MY_fun101
freq = 100000;
epsilon = 1119.2;
sigma = 0.00045128;
syms x y
eq1=x-1i*y==1119.2;
eq2=(2*pi*freq*y+sigma)/(2*pi*freq*x)==0.07248;
eqns=[eq1 eq2];
S=solve(eqns, [x,y]);
Solution = double([S.x, S.y]);
end
Note that the output variable Solution is defined inside the code that was the error in your code.
Good luck.
