5.1.120 regularity
Syntax:
regularity ( list_expression )
regularity ( resolution_expression )
Type:
- int
Purpose:
- computes the regularity of a homogeneous ideal, resp. module, from a
minimal resolution given by the argument.
Note:
- If applied to a non minimal resolution only an upper bound is returned.
If the input to the commands res and mres is homogeneous
the regularity is computed and used as a degree bound during
the computation unless option(notRegularity); is given.
Example:
See
list;
minres;
mres;
option;
res;
resolution;
sres.
