LinSyz.BettyNumber

computing a Betty Number for a Module, generated by linear forms

Syntax

$linsyz.BettyNumber(Module,Int):Int

Description

This command computes a the i-th Betty number of a given module, which is generated by vectors consisting of linear forms. Be aware of the fact that this is very new and may contain bugs! Also the linear forms may not have any constant component, so if your system has some, you have to make the system homogeneous first via introducing a new indeterminate.
