1Thu Jul 15 17:10:09 CEST 2010 dreyer:
2* ambigous overload of si_max resolved
3Fri Jan 19 17:56:20 CET 2001 hannes:
4* mod, div for intvec fixed
5* highcorner for global case fixed
6* highcorner for qring fixed
7Tue Feb  1 09:33:35 MET 2000 hannes: summary of changes
8* lift changed: - uses interanlly a different algorithm
9                  (for SB and NON-SB unified)
10                - can be used with an optional 3rd argument (a matrix name),
11                  if given, the "matrix of units" will be stored in it
12* new command: division (extension of lift)
13     division(M,SM) returns a list (T,U,R) with SM*U+R=M*T
14* new monomial ordering (internal change only):
15   use of inline function instead of a function pointer
16   (possible point for difficulties: mcompSchrB(polys.cc), pSetSchreyerOrdM
17   (polys.cc))
18* new Library:
19   spectrum.lib: interface to Stefan Endrass' spectrum routines
20   (Stefan Endrass/H.Schoenemann)
21   (still incomplete, requires a "special" Singular)

23   CaMuReg.lib: PROCEDURES FOR COMPUTING CASTELNUOVO-MUMFORD REGULARITY
24   Authors:I.Bermejo/Ph.Gimenez/G.-M.Greuel
25   (not included in the documemtation, not included in the tests)

27    - computes a free resolution of an ideal using Hilbert-driven algorithm

29  (not documented, not included in the documemtation, not included in the tests)
30
31Fri Aug 13 13:20:01 MET DST 1999 hannes
