BBF.RetrieveVPolysWithTermInSupport
Retrieves polynomials with specific support term from V.
Syntax
BBF.RetrieveVPolysWithTermInSupport(T:POLY):LIST
Description
Please note: The function(s) explained on this page is/are using the ApCoCoABBFServer. You will have to start the ApCoCoABBFServer in order to use it/them.
This command retrieves all polynomials from V that have the term T in their support.
@param T All polynomials in V with this term in their support will be retrieved.
@return List of polynomials of set V.
Example
Use ZZ/(32003)[x, y, z],DegLex; I:=Ideal(-4*x^2 + 1, -4*y^2 - 1, 5*z^2); BBF.Init(I); BBF.Steps(20); -- After computation has finished: BBF.RetrieveVPolysWithTermInSupport(z); Output: [x^2z - 8001z, y^2z + 8001z]
