Subject: [R] finding complex roots in R
I am looking for a way to find the roots of a non-polynomial
expression. I know R has a few ways to deal with polynomials, but, I
could not find a method that deals with functions involving e^(x) type
arguments, that have complex roots

Hi Toros,
It is actually quite easy to do this with existing real-root finders. If
you want to solve for F(z) = 0, where z = x + iy, you simultaneously solve
for the zeros of the real and imaginary part of F.
Here are a couple of examples

I am looking for a way to find the roots of a non-polynomial
expression. I know R has a few ways to deal with polynomials, but, I
could not find a method that deals with functions involving e^(x) type
arguments, that have complex roots as well as real roots.
Any ideas?
Thanks,
Toros
