Phcmaple: A Maple Interface to the Numerical Homotopy Algorithms in PHCpack. Our Maple package PHCmaple provides a convenient interface to the functions of PHCpack, a collection of numeric algorithms for solving polynomial systems using polynomial homotopy continuation, which was recently extended with facilities to deal with positive dimensional solution sets. The interface illustrates the beneØts of linking computer algebra with numerical software. PHCmaple serves as a Ørst step in a larger project to integrate a numerical solver in a computer algebra system
