BBF.Retrieve
retrieve objects from ApCoCoABBFServer
Syntax
$BBF.Retrieve(ObjectName:STRING):LIST
Description
Retrieve computed objects from ApCoCoABBFServer. The input to this function must be the name of the object to retrieve. If an object has not been computed yet an empty list is returned.
| ObjectName (as STRING) | Output |
|---|---|
| BBasis | List of polynomials representing a border basis. |
| L | List of monomials representing the generators of L. |
| O | List of monomials representing the generators of O. |
| V | List of polynomials used for computations in the Border Basis Algorithm. |
Please not that in order to use this function you have to start the ApCoCoABBFServer.
Beta Warning: This method, package or class is a beta version. It may not work as intended or its interface may change in the next version! So please be careful when you're intending to use it.
Example
Use Z/(32003)[x, y, z],DegLex;
I:=Ideal(-4*x^2, -4*y^2, 5*z^2);
$BBF.Init(I);
$BBF.Finish();
$BBF.Retrieve("BBasis");
Computation started.
