From help-request at octave dot org Tue Feb 1 09:51:51 2005 Subject: Question DASSL From: Kristof Timmermans To: help at octave dot org Date: Tue, 1 Feb 2005 09:28:58 -0600 Hello, I am using the function DASSL (in Octave 2.1.64) and I never had a problem. I use it to solve some differential equations. But today when I started a simulation I got following error: ***MESSAGE FROM ROUTINE DDASSL IN LIBRARY SLATEC. ***POTENTIALLY RECOVERABLE ERROR, PROG ABORTED, TRACEBACK REQUESTED * AT T = 3.447491E-05 SOME ELEMENT OF WT HAS BECOME .LE. 0.0 * ERROR NUMBER = -3 * ***END OF MESSAGE ***JOB ABORT DUE TO UNRECOVERED ERROR. 0 ERROR MESSAGE SUMMARY LIBRARY SUBROUTINE MESSAGE START NERR LEVEL COUNT SLATEC DDASSL AT T = 3.447491E- -3 1 1 error: exception encountered in Fortran subroutine ddassl_ error: unrecoverable error in dassl Is there anyone who knows what I should do, so I don't have a problem with the DASSL function? I don't find the necessary information to cope with this problem.
