## BB.GenHomMultMat

Computes a generic homogeneous multiplication matrix.

### Syntax

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

### Description

Computes the generic homogeneous multiplication matrix for `x[I]` 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 Len(OO) x Len(OO) over the ring `BBS=K[c_{ij}]`.

@param

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

*OO*A list of terms representing an order ideal.@return The generic homogeneous multiplication matrix.
