How to use Newton-Raphson for numerical solution of two variables?

Hello community,
I have a non-linear function f(x,y), which I would like to find the roots of with the Newton-Raphson method. However, I haven't yet found a simple code on the internet in case of two variables, which just lets me enter my function and get the result. If I find one, the solutions on the internet always need two equations, but I only have one?

Can i divide it into a real and an imaginary equation
You could just rewrite your function to return a 2x1 vector containing the real and imaginary part respectively.
If f() is your existing function, you could also do
f_new=[real(f(x,y)); imag(f(x,y))]
