Thank you Abigail and hello other monks, I think I will try to go from scratch. I want to build a matrix using a hash of hashes so that I can delete items easily afterwards without the matrix getting illformed. I find it hard to use the packages, because they require a certain input format. But I'm wondering now... can I do multiplication with a matrix that is built as a hash of hashes? -Choco
