I am trying to numerically solve a nonlinear complex equation and I would like to find all the complex roots. The equation is of the type:
cot(z)*z = 1-z^2*(1+i*z)
Does a specific function exist to find all the complex roots or do I need to separate z in the real and imaginary parts?
Thanks in advance for your help!
No products are associated with this question.
If you have the Symbolic Math Toolbox, I think SOLVE can be used to get complex-valued solutions. For the numerical solvers, I'm pretty sure you do have to reformulate the problem in terms of real and complex parts. Also, I've never heard of a numerical solver that will robustly find multiple roots for anything except polynomials.
