FastMinors package for Macaulay2

Boyana Martinova, Marcus Robinson, Karl Schwede and Yuhui Yao

Vol. 13 (2023), 13–31

In this article, we present FastMinors.m2, a package in Macaulay2 designed to introduce new methods focused on computations in function field linear algebra. Some key functionality that our package offers includes: finding a submatrix of a given rank in a provided matrix (when present), verifying that a ring is regular in codimension n, recursively computing the ideals of minors in a matrix, and finding an upper bound of the projective dimension of a module.
