* Package name : cxroots Version : 3.2.0 Upstream Contact: Robert Parini <[email protected]> * URL : https://github.com/rparini/cxroots * License : BSD-3-Clause Programming Lang: Python Description : find all roots of a function in the complex plane cxroots is a Python package for finding all the roots of a function, f(z), of a single complex variable within a given contour, C, in the complex plane. It requires only that both: f(z) has no roots or poles on C f(z) is analytic in the interior of C The implementation is primarily based on [KB] and evaluates contour integrals involving f(z) and its derivative f'(z) to determine the roots. If f'(z) is not provided then it is approximated using a finite difference method. The roots are further refined using Newton-Raphson if f'(z) is given or Muller's method if not. This is a damn useful package, augmenting the root finders of scipy.optimize, which only return one root. The package may be interesting to Debian Science users, but it's a general package for any mathematical application, so I think it is better maintained by the Debian Python team, alongside scipy.
