I try to make an optimisation with using DE
I have a function which changes with two variable. One of them is frequency,
other one is resistance

for example:
func=@(x,f)  x*f

I have an experimental data of "func" in frequency domain and I try to back
calculate x.

So I have for example;
exp_data=[200,400,600] as an experimental results. And I try to find best x
which satisfies

error_array=@(x,f) abs(func(x,f(index))-exp_data(index))^2; %error function
for each frequency
sum_error=@(x,f) sum(error_array(x,f)) % I try to minimize that function

So I use sum_error for DE search.
I hope thats clear.

did you read

why not make a function that returns sum_error and then use one of the functions on that page?

function ret=plant(x,f)
end function
