MPSolve (Multiprecision Polynomial Solver) is a package for the approximation of the roots of a univariate polynomial. It uses the Aberth method.
"Mpsolve takes advantage of sparsity, and has special hooks for polynomials that can be evaluated efficiently by straight-line programs
It uses command line interface (CLI).
The executable program of the package is called unisolve (univariate polynomial solver). It can be run from command line in console.
Typically output will be on the screen.
It may also be saved the to the text file (with res extension) and plotted in gnuplot.
This image shows centers of hyperbolic components of mandelbrot set for period 10 (and its divisors). There are also drawn boundaries of period 1 and 2 hyperbolic components.
It is made with gnuplot. Centers are computed with MPSolve.
