LRhomotopies -- interface to the Littlewood-Richardson homotopies in PHCpack

Interfaces the functionality of the software PHCpack to solve Schubert problems with Littlewood-Richardson homotopies, a tool in numerical Schubert calculus. The software PHCpack is available at The site provides source code and its executable versions phc. The user must have the executable program phc available, preferably in the execution path.


The program "phc" (at least version 2.4.27, but preferably higher) of PHCpack needs to in the path for execution.
