The documentation seems to be out of step with the code, maybe it is a change since 12.5.1, but the way cplexoptimset and cplexoptimget actually work is very different from that in the documentation, making it hard to figure out how to control the solver. e.g. how to stop the annoying print to the clone1.log file by cplexlp.m

>> cplexoptimset('cplex')

ans =

           advance: 1
           barrier: [1x1 struct]
         clocktype: 2
          conflict: [1x1 struct]
      dettimelimit: 1.0000e+75
          emphasis: [1x1 struct]
           feasopt: [1x1 struct]
          lpmethod: 0
               mip: [1x1 struct]
           network: [1x1 struct]
            output: [1x1 struct]
          parallel: 0
     preprocessing: [1x1 struct]
          qpmethod: 0
        randomseed: 201303143
              read: [1x1 struct]
           sifting: [1x1 struct]
           simplex: [1x1 struct]
    solutiontarget: 0
           threads: 0
         timelimit: 1.0000e+75
              tune: [1x1 struct]
           workdir: '.'
           workmem: 128
       diagnostics: 'off'
       exportmodel: ''

K>> ans.output

ans =

            clonelog: 1
    intsolfileprefix: ''
             mpslong: 1
          writelevel: 0

clonelog = 0 does not seem to work.
