Complex Root Finding
Description
Find the root of a complex function
Usage
fzsolve(fz, z0)
Arguments
fz
complex(-analytic) function.
z0
complex point near the assumed root.
Details
fzsolve tries to find the root of the complex and relatively
smooth (i.e., analytic) function near a starting point.
The function is considered as real function R^2 --> R^2 and the
newtonsys function is applied.
Value
Complex point with sufficiently small function value.

newtonsys
Examples
fz <- function(z) sin(z)^2 + sqrt(z) - log(z)
fzsolve(fz, 1+1i)
# 0.2555197+0.8948303i
