How to pass several anonymous functions to the anonymous fitness function in gamultiobj()?

Hi,

i want to optimize a problem with several objectives using gamultiobj(). I have 3 objective funtions, which i want to pass to the parameter fitnessfcn

The Matlab documentation for gamultiobj states, that this can e.g. be done like this:

fitnessfcn = @(x)[sin(x),2*cos(x)+2,4*tan(x)];

The actual objective functions, that I want to use are unfortunately not as straight forwart as sin(x) etc. and require more input:

objective1 = @(x) minimize_val1(x,input);
objective2 = @(x) minimize_val2(x,input);
objective3 = @(x) minimize_val3(x,input);

How do I pass those 3 anonymus functions to the fitnessfcn?

Thanks in advance!

objective1 = @(x) minimize_val1(x,input1);
objective2 = @(x) minimize_val2(x,input2);
objective3 = @(x) minimize_val3(x,input3);

fitnessfcn = @(x)[objective1(x),objective2(x),objective3(x)];

or, even more directly,

fitnessfcn = @(x)[minimize_val1(x,input1),...
                  minimize_val2(x,input2),...
                  minimize_val3(x,input3)];
