How to modify this function with a different objective function

From this tutorial on Multiobjective Optimization using Particle Swarm Optimization, there is a function that creates the two objective functions (below). My question is: I have two objective functions that I would like to replace f1 and f2 with, but I am unsure where to even begin. For example, my objective functions are the Sharpe Ratio and Percent Profit functions. Both of these functions require a couple different inputs and I am not sure where these should be initialized.

Any support on where to go next is appreciated!

function z=ZDT(x)

    n=numel(x);

    f1=x(1);

    g=1+9/(n-1)*sum(x(2:end));

    h=1-sqrt(f1/g);

    f2=g*h;

    z=[f1
       f2];

end

That is, create two anonymous functions

   extra_parameters_for_sharpe = ....
   extra_parameters_for_percent_profit = ....
   F_sh = @(x) sharpe_ratio(x, extra_parameters_for_sharpe);
   F_pp = @(x) percent_profit(x, extra_parameters_for_percent_profit);

After which,

obj = @(x) [F_sh(x); F_pp(x)];
best_x = particleswarm(obj, .......)

Makes sense, thanks Walter! Another question... Would x and the extra parameters be the weights for the objective functions that are returned when the swarm is finished optimizing? And is there a way to turn this Sharpe Matlab function into an objective function for my optimization code? ( Sharpe Ratio)
