## 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]
