how to use arrayfun for gpu

Hi there, I am calling a function which is a sample used from a matlabs webinar:

for n = 1:100

    for m = n:100

        [~,~,sh(n,m)] = leadlag(Close,n,m,annualScaling, 0.0006);

    end

end

How do I alter this so that gpu is using arrarfun to speed it up?

In general, arrayfun allows you to speed up cases where you have lots of elementwise operations to perform. You need to look inside the 'leadlag' function to try and find places where arrayfun can be applied.
