Im trying to find 4(x in this case) variables that minimize my function, I have my function defined as:
function z = my_fun(x, y, t)
z = sum((y-(A + B.*(x(1)-t).^x(2) + C.*(x(1)-t).^x(2)).*cos(x(3).*log(x(1)-t)+x(4))).^2);
y and t are two vectors of the same length which I already have.
When I try to run the algorithm Matlab says: "Not enough input arguments." Anyone has any idea how to solve this? Thanks in advance!!!

You didn't show us your call to ga, but the way you are supposed to call a function with extra parameters (your y and t) is this:
x = ga(@(x)my_fun(x,y,t),4)

Thank you very much!!! that seems to have solved my problem. Do you happen to know how I can do the same within the "gatool" interface?
And is there a way for the GA to ignore the A, B, C variables? As I would like to compute them later in a linear regression when I have the values of the other x variables.

hi sir I have assignment to use estimation using lppl, can you send me matlab code for lppl with genetic algorithm.

Most probably, you are trying to use the run button from the editor. You don't use run on functions. Only on scripts. (Really run should be disabled for functions.)
Or maybe you are trying to use this function in some other way. Maybe you just typed in my_fun in the command window with no arguments.
