I need to perform kriging in Matlab based on three borehole samples.
Numbers for soil layers indicate depth from ground zero, boreholes - position on model.
The outcome should look something like this (already done that in Zsoil):
Any ideas how to perform this?

No, these are commas all right. 3,27 is one value. It means soil layer 1 ENDS at depth of 3,27 meters, as measured from the surface level.
Similarly soil layer 3 ends at 8,95 meters and so on.

no need to be rude a comma is a common point in europe. to auther though thsi is matlab if you are using decimalisation you must use decimal points. commas are seperators in matlab and will fail if you mix and match

Googling "MATLAB" and "kriging" turned up this submission from the File Exchange.

Sorry, but I am completely ignorant of this method, so I can't really give you a better "hint" than providing you with a pointer to code where someone else solved the problem. I would have hoped that this would give you a solid headstart on writing your own.
I hadn't noticed how old the submission I mentioned was. There are other kriging examples in the File Exchange, that look more up-to-date. Maybe they will be more helpful.

Thanks anyway for your effort. Maybe the thread will attract someone who had similar exercise.

I believe I saw somewhere in the documentation that scatteredInterpolant did kriging. Attached is a demo.

Actually, I don't understand why you need kriging here. The figure created by Zsoil shows a linear interpolation of the individual depths above which soils are classified into the respective soil layers. Kriging won't help here, inparticular since you would need to have a variogram.

I do not deny what you say is right. But student exercises do not always make sense. I am supposed to use kriging in matlab, not only zsoil...
