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.
I find this remark curious as the floyd_warshall sub can take a reference to a hash of hashes as argument.
can I do multiplication with a matrix that is built as a hash of hashes?
Sure, but you probably have to code it yourself.
