D.15.6.4 determinacy

Procedure from library realclassify.lib (see realclassify_lib).

Usage:
determinacy(f[, mu]); f poly, mu int

Return:
an upper bound for the determinacy of f

Note:
The characteristic of the basering must be zero, the monomial order must be local, f must be contained in maxideal(1) and the Milnor number of f must be finite.
The Milnor number of f can be provided as an optional parameter in order to avoid that it is computed again.

Example:
 
LIB "realclassify.lib";
ring r = 0, (x,y), ds;
poly f = x3+xy3;
determinacy(f);
==> 5
