New version of CoStLy
by Markus Neher 28 Oct '04

28 Oct '04

Dear colleagues, a new version of the CoStLy library for complex inclusion functions is available now. The whole library has been redesigned completely. All of the "usual" standard functions have now (almost) optimal accuracy. There are new power functions with (almost) optimal accuracy and new root functions with (almost) optimal accuracy. The code and a paper describing the library are available at http://iamlasun8.mathematik.uni-karlsruhe.de/~ae16/CoStLy.html Best regards, Markus

New version of CVS
by Roberto Bagnara 19 Oct '04

19 Oct '04

Version 1.11.17 (client/server) of CVS has been installed on both cvs.cs.unipr.it and sandbox.cs.unipr.it. This, in turn, required the upgrade of cvsweb on www.cs.unipr.it to version 3.0.2. If you spot any anomaly, please let me know immediately. Please, consider upgrading your local CVS installation to the same version: go to http://www.cvshome.org. For those of you with ix86 GNU/Linux distributions that use RPM packages: here is what you need: https://ccvs.cvshome.org/files/documents/19/360/cvs-1.11.17-1.i386.rpm Cheers, Roberto -- Prof. Roberto Bagnara Computer Science Group Department of Mathematics, University of Parma, Italy http://www.cs.unipr.it/~bagnara/ mailto:bagnara@cs.unipr.it
