BB.GenMultMat

Computes a generic multiplication matrix.

Syntax

BB.GenMultMat(I:INT,OO:LIST):MAT

Description

Computes the generic multiplication matrix for the I-th indeterminate with respect to an order ideal. The second element of OO must be a non-constant polynomial. The output is a matrix of size Len(OO) x Len(OO) over the ring BBS=K[c_{ij}].

• @param I An integer which specifies the indeterminate for which the generic multiplication matrix will be computed.

• @param OO A list of terms representing an order ideal.

• @return The generic multiplication matrix.
