The MatrixSchubert package for Macaulay2
We introduce the MatrixSchubert package for the computer algebra system Macaulay2.This package has tools to construct and study matrix Schubert varieties and alternating sign matrix (ASM) varieties.The package also introduces tools for quickly computing homological invariants of such varieties, finding the components of an ASM variety, and checking if a union of matrix Schubert varieties is an ASM variety.
