MATLAB: Ga function Input data

Question

Hey, I wish to use ga optimization for a given function.

I want to send an "extra" variable to the function that is not part of the optimized variables

basically: I have a function

 function f=FindAC(x,val)

X is a 2X1 vector that I want to find the optimized value val is just a long array of input data

I tried:

 ga(@(x,val)FindAC,2,[],[],[],[],lb,ub,[],intcon)

but I get error message

 Not enough input arguments.

needless to say that without the ga optimization :

 f=FindAC(x,val)

the function runs without errors

how can I send "val" to the function while asking the ga to optimize x

Answer 1

Try making ‘FindAC’ a function only of ‘x’ for ga:

ga(@(x)FindAC(x,val),2,[],[],[],[],lb,ub,[],intcon)

This a guess, since I am not certain what the problem is.
