Dear Gap forum, there are two functions, which are reasonably basic, which would perhaps be useful to have in GAP: ---Pfaffian of an antisymmetric matrix. ---sylvester inertia coefficients of a symmetric matrix.
I can contribute myself those functions, but the code may not be up to the standard of GAP. Mathieu -- Mathieu Dutour Sikiric Researcher in Math Tel. (+972)2 65 84 103 and Computer Science Fax.
