Singular Manual: ncloc_lib

> | ### 7.5.17 ncloc_lib Library: ncloc.lib Purpose: Ore-localization in G-Algebras Author: Johannes Hoffmann, email: johannes.hoffmann at math.rwth-aachen.de Overview: This library introduces a new type: ncloc. This type wraps the localization data defined as in olga.lib. An element of type ncloc has two members: - int locType - def locData Operations: string(ncloc); give a string representation of the data describing the localization print(ncloc); prints the string representation of the localization status(ncloc); report on the status/validity of the localization test(ncloc); check if the localization is valid Infix operations: ncloc == ncloc; compare two localizations ncloc != ncloc; compare two localizations ncloc = list/poly create a monoidal localization from the given data ncloc = ideal create a geometric localization from the given data ncloc = intvec create a rational localization from the given data Procedures:
> 7.5.17.0. isDenom |  | determine if a polynomial is in the denominator set of the localization
> 7.5.17.0. testNcloc |  | execute a series of internal testing procedures
> 7.5.17.0. testNclocExamples |  | execute the examples of all procedures in this library
