Overview:
A library for classifying isolated hypersurface singularities w.r.t. right equivalence, based on the determinator of singularities by V.I. Arnold.

Procedures:

D.5.1.1 basicinvariants  computes Milnor number, determinacy-bound and corank of
D.5.1.2 classify  normal form of poly f determined with Arnold's method
D.5.1.3 corank  computes the corank of f (i.e. of the Hessian of f)
D.5.1.4 Hcode  coding of intvec v according to the number repetitions
D.5.1.5 init_debug  print trace and debugging information depending on int n
D.5.1.6 internalfunctions  display names of internal procedures of this library
D.5.1.7 milnorcode  Hilbert poly of [e-th] Milnor algebra coded with Hcode
D.5.1.8 morsesplit  residual part of f after applying the splitting lemma
D.5.1.9 quickclass  normal form of f determined by invariants (milnorcode)
D.5.1.10 singularity  normal form of singularity given by its name s and index
D.5.1.11 swap  returns b,a
D.5.1.12 A_L  shortcut for quickclass(f) or normalform(s)
D.5.1.13 normalform  normal form of singularity given by its name s
D.5.1.14 debug_log  print trace and debugging information w.r.t level>@DeBug
