Hello,

I have to send some additional arguments to my objective function fun.

If I do this, I get an error saying that I have too many input arguments.

[xn3,fvaln3,exitflagn3,outputn3] = particleswarm(@fun,nvars,lb,ub,options, additionalArguments);

Then I tried the following thing but I got an error saying I can't have a structure as an input argument.

   [xn3,fvaln3,exitflagn3,outputn3] = particleswarm({@fun,additionalArguments},nvars,lb,ub,options);

Thanks in advance!

That older way of passing additional arguments is supported but not documented for older functions. Newer functions do not support it at all.

For supported, documented ways of passing extra parameters, see the documentation.

simulannealbnd does not have A, b, Aeq, beq or nonlcon arguments .

[Param,fval, exitflag,output] = simulannealbnd(f, Param0, LB, UB, options);

You cannot add additional arguments to matlab predefined functions. click hrer for more about particleswarm

For other optimisation algorithms and functions I have no problem sending the additional parameters in the two ways I mentioned, i.e. I used the second way in pattern-search.
