extracting specific grid country from a netcdf file

Hello all. I have downloaded a nc file from this link (you need to make an account in order to download it)

What i want is to extract and print the difference in temperature over the years in one specific country (for example Italy)

I am a bit confused on how to do it since i am really new to matlab.

I have found a similar question however i could not make it work for my case. example

The problem is I cannot understand these commands properly and what exactly I should insert/replace from my data

unitsTime = info.Variables(3).Attributes(1);

unitsPrep = info.Variables(4).Attributes(3).Value;

validRangePrep = info.Variables(4).Attributes(2).Value;

labelPrep = info.Variables(4).Attributes(1).Value;

Probably no one is going to make an account there just to help you. Make it easy for people to help and maybe someone will.

I tried to upload the data but the size is too big, even if I zip it. Any idea how to proceed?
