12 Aug 2013 Experimental (Semi-) Variogram calculate the isotropic and anisotropic experimental (semi-) variogram Author: Wolfgang Schwanghart

Hi Wolfgang,
Yes, that's a decision that concerns me these days, because either I use one variogram per time sample or as i have a lot of timesamples, I can do a training phase for kriging and I get a variogram characteristic from the system, which I will use in the test phase. I am currently working on my own 3d kriging and i wanted to compare results.
Thank you very much!

Hi again,
I just realize the NaN make sense in my data.
But still i have some questions.
Once I already know that variogram can work with 3d input, I tryed the kriging script but it seems like the input is 2dimensional, is there a way to use 3D data on the kriging script?
I am working with temperature samples along a period of time, and i wonder if i can in the variogram function give as values the entire time samples matrix, instead only one time sample only.
I hope i am being clear enough.
Thank you so much

Thank you so much Wolfgang!
I tried and at the beginning i had an error but i changed what @Shen said
d = sqrt(sum((X(i,:)-X(j,:)).^2,2));
and it worked, but the d.val has a lot of NaN, is that OK? because I have very bad fits on the variogramfit script.
Thanks again

Hello Wolfgang,
I am trying to apply Kriging to a 3d mesh but first of all i don't know if i can use your variogram from a 3d data, it seems that only accepts X ans Y, not Z coordinates. Is there any way to use it with 3d input?
Thank you very much
Ricardo
