You would have to pass the entire list in the option, or have a separate option for each element. It might be better to write the definition of your function as f[a_,b_,c_][variables__]:=.... and then just feed in the particular values you want when you call it. You could even make a, b and c optional arguments.

I tried to change, for example, 'a' to 'd' like this: SetOptions[f,pars[[1]]->d] But it didn't work. I also tried to access the option: Options[f,pars] And the result is: {} Does anyone know what am I doing wrong or if it's not possible at all to have a list as an option? Thank you!!
