    Re: signature

    Grammatically, "signature matrix" and "matrix signature" are two different things!

    According to the website jbunniii references, the "signature of a matrix" is an order triple of integers: (the number of positives entries on the main diagonal, the number of negative entries on the main diagonal, the number of 0 entries on the main diagonal).
