[GAP Forum] how to use the hilbert function after loadpackage singular

[Lee Martin CCNP]

Hi 
http://www.gap-system.org/Manuals/pkg/singular/doc/chap1.html#X795A815178AA90C7
in manual of singular interface in gap system
i can not find the function name for hilbert function
it seems can use function with singular package, what is the function name of hilbert function in gap system? and how to use to use it?
Regards,
Martin
