We describe a new software package for computing multiplier ideals in certain cases,
including monomial ideals, monomial curves, generic determinantal ideals, and
hyperplane arrangements. In these cases we take advantage of combinatorial
formulas for multiplier ideals given by results of Howald, Thompson, and
Johnson. The package uses the package
Normaliz. It is available as a library for
Macaulay2.
