I have 10 .mat files with 5 variables each. I want to load them automatically in MATLAB into one Matrix were the values of the variables are inserted one after another. And I want to insert a counter on the right that tells me the number of the file.
[Var1 Var2 Var3 Var4 Var5 Counter
Valfile1 Valfile1 Valfile1 Valfile1 Valfile1 1
Valfile1 Valfile1 Valfile1 Valfile1 Valfile1 1
Valfile1 Valfile1 Valfile1 Valfile1 Valfile1 1
Valfile2 Valfile2 Valfile2 Valfile2 Valfile2 2
Valfile2 Valfile2 Valfile2 Valfile2 Valfile2 2
Valfile2 Valfile2 Valfile2 Valfile2 Valfile2 2
...
Is that possible with a for loop?

Yes it is possible. You just have to print the index indicating from which file you are currently loading the data. You can see the sample code given below:
k = [];
FileName = {'file1.mat','file2.mat','file3.mat'};
for i = 1:3
k = [k; importdata(FileName{i}) i*ones(5,1)];
end
