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?

请先登录，再回答此问题。

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.
