Hi Hans, It appears that the output.clonelog = -1 did not work due to a CPLEX bug that has been fixed in 12.6.0.1. Information on the “fix pack” can be found here.
I have confirmed that the clone1.log files are no longer created with CPLEX 12.6.0.1 if I add … opt.output.clonelog = -1; … at line 129 of cplex_options.m, which I have done for the next MATPOWER release. -- Ray Zimmerman Senior Research Associate B30 Warren Hall, Cornell University, Ithaca, NY 14853 USA phone: (607) 255-9645 On Jul 21, 2014, at 1:10 PM, Ray Zimmerman <[email protected]> wrote: > Unfortunately, unless I’m missing something, I don’t think CPLEX offers a way > to turn off the log file completely via the Matlab interface.
