Package mpsolve

https://numpi.dm.unipi.it/software/mpsolve

MPSolve stands for Multiprecision Polynomial SOLVEr.  It aims to provide
an easy to use universal blackbox for solving polynomials and secular
equations.

Its features include:
- Arbitrary precision approximation.
- Guaranteed inclusion radii for the results.
- Exploiting of polynomial structures: it can take advantage of sparsity
  as well as coefficients in a particular domain (i.e. integers or
  rationals).
- It can be specialized for specific classes of polynomials.  As an
  example, the roots of the Mandelbrot polynomial of degree 2,097,151
  were computed in about 10 days on a dual Xeon server.

This package contains command-line interfaces to mpsolve.
