BBSGen.Wmat
This function computes the Weight Matrix with respect to the arrow grading.
Syntax
WMat(OO,BO,N): WMat(OO:LIST,BO:LIST,N:INTEGER):MATRIX
Description
@param The order ideal OO, the border BO and the number of Indeterminates of the Polynomial Ring.
@return Weight Matrix.
Example
Use R::=QQ[x[1..2]]; OO:=BB.Box([1,1]); BO:=BB.Border(OO); N:=Len(Indets()); ---------------------- W:=Wmat(OO,BO,N); W; Mat([ [0, 2, 1, 2, 0, 2, 1, 2, -1, 1, 0, 1, -1, 1, 0, 1], [2, 0, 2, 1, 1, -1, 1, 0, 2, 0, 2, 1, 1, -1, 1, 0] ])
