Hello all,
I am trying to use the following package:
https://www.mathworks.com/matlabcentral/fileexchange/86852-autocorr2-two-point-autocorrelation
However, whenever I try to run it, the memory consumption gradual increases until the device freezes, I tried alternating the parameters, same results.
Any idea what is causing this huge memory consumption?, knowing that I run heavier packages with no issues.
Thank you and stay well.

I have no problem with running the function to get an auto-correlation for images with 1000x1000 pixels.
Again: What do you use as inputs?
This code does not look "heavy":
x = [];
for k = 1:1e6
x(k) = k;
end
Due to the missing pre-allocation Matlab has to allocate more than 4 TB of RAM to run this code.

I see what you mean now.
I will edit it so it allocates less than that.
Thank you so much!
