phcpack binary package in Ubuntu Lunar s390x

 PHCpack is a software package to solve polynomial systems by homotopy
 continuation methods.
 .
 A polynomial system is given as a sequence of polynomials in several
 variables. Homotopy continuation methods operate in two stages. In
 the first stage, a family of polynomial systems (the so-called
 homotopy) is constructed. This homotopy contains a polynomial system
 with known solutions. In the second stage, numerical continuation
 methods are applied to track the solution paths defined by the
 homotopy, starting at the known solutions and leading to the solutions
 of the given polynomial system.
 .
 This package contains the command line interface to PHCpack.
