Does any body has good subroutine to find the complex roots of following
equation numerically:

F(q)=0, where the q is a complex number.

Any suggestion and help will be really appreciated.

Thanks for help.

     Pachner has a well-behaved Newton-like method for this.  Look for
his "Handbook of Numerical Analysis Applications".
