py311-pyneqsys

Solver of symbolically defined systems of non-linear equations

pyneqsys provides a convenience class for representing and solving non-linear equation systems from symbolic expressions (provided e.g. with the help of SymPy). The numerical root finding is perfomed using either: * scipy: scipy.optimize.root * mpmath (arbitrary precision): mpmath.calculus.optimization.MDNewton * kinsol (from SUNDIALS): pykinsol.solve * nleq2 (ZIB library free for academic use): pynleq2.solve * levmar (Levenberg-Marquardt): levmar.levmar In addition to offering a unified interface to different solvers, pyneqsys can also derive the Jacobian analytically (when using pyneqsys.SymbolicSys). This is useful since doing so manually is widely recognized as both tedious and error prone.
