Hi,

I have written a script that uses pdl to do some linear algebra computations. In the same script, I'm trying to do a linear algebra computation using the matrix class in polymake.

The issue I'm encountering is that when I apply det to a polymake matrix, it does the pdl det and gives an error. I want to use the polymake det function because I'm running into numerical precision issues with the pdl det (if I replace all the matrices by pdl matrices).

Is there a way to tell polymake to use the polymake det function? If not, is there is an efficient way to compute the multiplicity of a set of integer vectors (i.e., the index of the subgroup of lattice points they generate in the group of lattice points in the vector space they span) in polymake?

Thank you!
