Hey, you need to save the values inside for loop. You can do it either by creating a bigger x matrix with n rows and 3 columns so you can finally use table(x) to create a table or you can add rows to a predefined table inside the for loop.
T = table;
for n = 1:10
x = P*x+q;
x_t = table(x(1),x(2),x(3));
T = [T; x_t];
end
T.Properties.VariableNames = {'x' 'y' 'z'};
