D.5.1.7 milnorcode

Procedure from library classify.lib (see classify_lib).

Usage:

milnorcode(f[,e]); f=poly, e=int

Return:

intvec, coding the Hilbert function of the e-th Milnor algebra of f, i.e. of basering/(jacob(f)^e) (default e=1), according to proc Hcode

Example:

LIB "classify.lib";
ring r=0,(x,y,z),ds;
poly f=x2y+y3+z2;
milnorcode(f);
→ 1,1,1
milnorcode(f,2);  // a big second argument may result in memory overflow
→ 1,0,1,0,2,0,0,1,0
