BB.GenMultMat
Compute a generic multiplication matrix.
Syntax
BB.GenMultMat(I:INT,OO:LIST):MAT
Description
Computes the generic multiplication matrix for <formula>x[I]</formula> with respect to an order ideal. The inputs are an integer I and a list OO of terms that specify an order ideal. The second element of OO must be a non-constant polynomial. The output is a matrix of size <formula>Mu<times/>Mu</formula> over the ring <formula>BBS=K[c_{ij}]</formula>.
@param I The generic ultiplication matrix for the indeterminate x[I] will be computed.
@param OO A list of terms representing an order ideal.
@return The generic multiplication matrix for the indeterminate x[I] over the ring BBS=K[c_{ij}].
