InverseSystems :: toDual

toDual -- finds the inverse system to an ideal up to a given degree

Synopsis

Description

If I is an ideal, then toDual(d,I) = inverseSystem(d, I). See the documentation of InverseSystems for the basic theory and of inverseSystem for the function.

If I is a matrix, then the code first replaces it with the ideal generated by the entries.

Caveat

The Base ring of the input must be a standard graded polynomial ring over a field.
