> | ## 7.5 PLURAL libraries The content of libraries, created for PLURAL is described in the following subsections. Use the `LIB` command for loading of single libraries. Note: For any computation in PLURAL, the monomial ordering must be a global ordering. See also jacobson_lib for the diagonalization of matrices over Ore Euclidean domains.
