You will need to provide the covariance (or variogram) structure, the up-scaling matrix G and the coarse scale value Z. See example folder for details of the methods and script.m for example how to use the function.

Hi Jinhao, sorry for the late reply, I did not revived any notification about your questions. Could you give a bit more detail about the issue?
Maybe, start reading https://rafnuss-phd.github.io/A2PK/ and have a look at the exemple. If you still have issue, could you send an issue on the github (https://github.com/Rafnuss-PhD/A2PK/issues) with the script you are using to call the function ?
Hope I can help you
Hi,Raphael,have you run this code successfully ? Unfortunately, I encounterd with many errors when I run it . I wonder if it's convenient for you to send me a complete code on one case, thank you. My E-mail is: email@example.com
correct FGS and more efficient computation of G
Faster computation of the weights, cleaner code.
