I use optimset to add a new entry to the options struct.  Entry "n" got into
the options as "niter_check_tolfun" silently.  

I cannot find the optimset documentation related to niter_check_tolfun.  
Therefore, I don't know if the output below is expected.  

Thanks, 

>> options=optimset('n', 100)
options =

  scalar structure containing the fields:

    niter_check_tolfun = 100
