Hi, I cannot access to some values of parameters of ga as (names = values hereafter) :

options_ga.FitnessScalingFcn = @fitscalingrank

options_ga.SelectionFcn = {@selectiontournament, 4}

In the latter, I can access the 2nd parameter, but not to the function handle. I need to write the parameters of ga in an .xlsx file using xlswrite, that is done easily except for the function handles in the 2 examples above. I tried some conversions that didn't work. Thanks in advance for your help !
