Hello
i would like to create objects in a for loop, where it get his number through an input of his number. In another for loop the object should be called with the help of the number and the properties should be set. How it can be done?
Thank you in advance!

Just use a regular for loop with indexing. E.g.,
for k=1:n
x(k) = myclass(whatever initialization is appropriate goes here);
end
Then you can set properties downstream. E.g.,
x(1).prop1 = something;
x(2).prop2 = something_else;
etc.

How can this be done for a gprfit class? For example, this is not possible:
for i = 1:10
gpr(i) = fitrgp(X,Xdot(:,i));
end
Thanks,

If the class in question doesn't allow users to store them in an array, put them in a cell array instead. For instance, you can't put function handles in an array but you can put them in a cell array instead.
c = cell(1, 3);
for k = 1:3
c{k} = @(x) x.^k;
end
c{3}(7) % 7^3 = 343
% this code WON'T work
a = @(x) x.^1;
a(2) = @(x) x.^2;
